You spend the rest of the evening in front of the TV, your notebooks and a whole gaggle of pencils laid out on the coffee table before you. Whatever notes you manage to take during your meetings with Jeongguk aren't exactly as neat as you'd preferâor even entirely legible, if you're being honest. But now, alone on the floor in your apartment with the news on in the background, you take the time to go through your scribbles and transfer them neatly into your Nice Notebook, the one that also contains all your drawings.
It takes you an hour, mostly because you keep going back and forth regarding the layout, but when everything's transferred, you can't help but grab your favorite graphite pencil. It glides over a fresh page, depicting something you've had a hard time letting go since you saw it.
Another hour, maybe one and a half, and they're there: Jeongguk's laser-focused black eyes. Not pictured: the paperclip.
You keep going, and not long after, the next page contains a profile portrayal of his upper teeth. The central incisor, the lateral one, and then the long, thin, clearly superhuman canine. Behind it, you can glimpse the regular canine.
At nine-thirty pm, you're unlocking the heavy door, peering around carefully. There are no inpatient animals tonight, meaning the clinic should be entirely empty. Also meaning: you have no business inside the building.
Thus, it's dark as you enter, and you only turn on what light you absolutely need as to not risk being found out if any of your colleagues were to drive pastâor God forbid, return to retrieve something forgottenâand see the place lit. Walking through the quiet corridors, you note that you have approximately twenty-five minutes to prepare.
At five minutes to ten, your phone dings. Since your outfit for once consists of something other than scrubs, you grab the device from your jean pocket to read the text displayed on the screen.
Jeon Jeongguk: I'm here
You don't reply, just stand from the chair you've been sitting on to note down some things, and head toward the entrance.
Like so many times before, you spot the tall, dark shape waiting just outside the door as soon as you enter the reception area, your heart skipping an excited beat.
With quick fingers, you unlock the door, and then you're peering up at him.
"Hi," you greet, backing up and watching as he steps inside, a tiny gust of wind accompanying him and making goosebumps rise on your arms.
He's wearing black again. A black leather jacket over a black shirt, and dark-wash jeans of the looser kind.
"Hi," he echoes, smiling down at you. His hair is windswept, and you swear his eyes might be even darker than last time you saw him.
You'd say you're quite a talented artist, but God, your drawing of his eyes is nothing compared to the real thing. You almost want to ask him whether all vampires are beautiful because you do remember his friends at the bar, and they were gorgeous as well.
"This way," you say, turning around.
Wordlessly, Jeongguk follows as you lead the way back to the room where he first apologized with the empty crate. Should someone, for some reason, visit the clinic, you'll be safest from discovery hidden away in the farthest room.
Keeping a distance of around a meter or so, Jeongguk's boots thump heavily against the floor as he trails behind you, a sound you're almost starting to find comfort in.
The door to the exam room is open, just like you left it, the light from inside pouring out into the otherwise dark hallway. You enter, shutting the door behind you when Jeongguk's through as well. You're not surprised to see him take his usual spot on the exam table, removing his jacket and folding it to lay beside him.
"You know, you can say no to this, right?" you ask, grabbing the sterile sheet of supplies you've prepared from the counter and placing it on the table next to him.
"It's fine. Consider it my apology for scaring you," he smiles warmly at you.
You return his gesture, pulling on some nitrile gloves.
"I'm very grateful. This is likeâŠ." you don't even know what to say as you drag the chair closer to him with your foot, sitting down and grabbing an antiseptic wipe to wipe down the inside of the elbow he wordlessly offers you. His skin is warm, radiating heat even through the gloves. "I feel like I'm the vampire, essentially vibrating at the thought of your blood."
He laughs at that, a lovely deep sound that goes straight to your heart.
"Well, I definitely don't need a tourniquet," you then mumble as you focus on his thick arm, pressing two fingers to the biggest vein and feeling it react almost like that of a human. It does give under pressureâbut much less than a human'sâquickly filling back up when you let go.
"Do you think this will work?" you ask, grabbing a needle and holding it up for him to see. It's one designed for the largest of dogs; the next step up in strength from a human grade needle.
"I don't know? I've never had my blood drawn."
Your eyes widen. "Really?"
You guess it makes sense, but it's still a surprise to hear.
"Yeah. Not really any use for it. And it wasn't really a thing when I was human."
"You sure you want to?"
"Yeah. How bad can it be? I'm not scared of pain or anything."
"Okay. Then I'll try with this one. It's usually a straight forward process, especially with veins like yours when you don't have to search for them. Or in my case, shave and search for them while holding the patient still."
Jeongguk grins.
"I'll try sticking you, and if it works, then I'll fill a few of these," you nod toward the vials on the blue sheet. "When I'm done, I'll remove the needle."
"Sounds good."
"Great."
Biting your lip, you focus on the needle as you angle it properly against the thick vein. You can't tell if Jeongguk is looking at your hands or your face, but you try not to think about his eyes on you.
Even though you've established that his skin doesn't feel too different from a human's besides the temperature, the needle is met with a surprising amount of resistance.
"Tell me if you want me to stop, okay?" you mumble, a little worried by the amount of pressure you're slowly forced to apply. You really don't want to accidentally stab him if his skin suddenly gives way.
Jeongguk only hums, clearly not that bothered. Slowly and very, very carefully, you increase the pressure, and then, the needle finally pierces through.
Relieved, you turn to the gathered equipment, reaching for some tape to fasten the needle against his skin, and then you're grabbing the first vial, attaching it.
Immediately, there's blood. It trickles in quicker than it would for an animal, or how you've seen your own blood do whenever you've had it drawn, and when you lean in, you notice that it's almost black. The gears inside your head are turning as you consider what it might mean. There's still a slight hint of redâa very dark red, which makes you wonder if his red blood cells are simply so tightly packed thatâ
Barely having time to finish the thought, you have to reach for the next vial, seeing the current one practically already filled to the brim.
Removing the full vial, you attach the new one, glancing up at his face when you're done. "Feeling okay?"
He nods and smiles softly, as if he realizes your (most likely very unnecessary) words are meant to be caring and not infantilizing.
"God, it smells of iron." You point out, blinking in surprise.
Jeongguk laughs. "Yeah. The iron also makes it a lot darker than human blood."
"I can see that," you say, replacing the second vial with the third and last one. "It looks like it's slightly more⊠viscous too," you comment, turning that second vial upside down. As you do, the blood pools at the new bottom, leaving a coat of dark red behind. Although it moves slower, its consistency is far from that of syrup; just a tiny bit less watery than your own blood.
"What are you going to do with them?"
"I'm bringing them home with me just so that no one sees them. I'll be looking at⊠Well, whatever I can see. Usually, putting a drop of blood under a microscope will let you see the red and white blood cellsâwhich carry oxygen and keep one's immune system working, respectivelyâand then the platelets and plasma.
"Platelets can show things like how quick the body can heal a wound and plasma is basically the liquid that holds the proteins and electrolytes. So I'll be looking at shapes, amounts, and behaviors of the cells. Other than that, I can't really plan ahead because I have no idea what I'll see."
He nods, and you remove the last vial, placing it next to the other two on the sheet beside him. Giving him a quick warning, you then swiftly remove the needle, prepared to wipe any escaping blood with a bit of gauze. But there isn't any; not even a tiny pink dot remains as evidence.
"UhâŠ" you continue, trying to find your thoughts again as you peer between his flawless skin and the needle you definitely know you just pulled out. "Right⊠And if I can manage to do it without anyone noticing, I'd also love to analyze some of your blood here at the lab.
"I won't be able to look at the proteins themselves with my microscope at home, but I am particularly curious about them and why you can be so warm without the proteins in your blood essentially cooking. And also whether the lead poisoning you described has left any visible traces. And, of course, to see just how much iron is in your blood and whatnot."
You stand up, disposing the needle in the sharps container and remove the gloves to throw them in the trash. When you're done, you grasp two of the three vials from the table, backing toward the door. "I'll be right back, I'm just gonna put these in the centrifuge."
"Alright."
The dark hallways don't pose a problem for you, knowing every door and every turn like the back of your hand. Therefore, it doesn't take you more than a minute or two to locate the lab with the desktop centrifuge, popping the two vials in and starting the machine. It comes to life with a hum, and you leave the room to let it work in peace.
When you return to the exam room, Jeongguk is standing in front of the ultrasound machine you rolled into a corner prior to his arrival. It's an older model, bulky and ancient compared to the portable ones you take out into the field.
While he's watching that, you're watching him, having an embarrassingly hard time tearing your eyes from his wide, muscular back. And even though you just got to sit eye to eye with his veins, your gaze trails those veins spanning the back of his forearms almost hungrily. God, you can't remember the last time you had a crush like this. Wait, what?
"You wanted to use this one, right?" Jeongguk interrupts your thoughts as he gestures toward the machine, still inspecting it curiously.
"YeahâŠ" you confirm. He keeps looking at the machine as you retrieve the rest of the blood draw supplies, setting them on the counter along with the third vial; the one you're keeping un-centrifuged for your microscope at home.
"âŠBut what?" he asks when he notices the slight hesitancy, looking back at you to see you leaning back against the counter, crossing your arms and biting your lip as you think.
"Well⊠your heart was a little hard to hear with the stethoscope, and considering everythingâlike how strong you evidently areâI'm just wondering if⊠maybe your muscles are somehow so dense that it's harder for sound to penetrate them?"
"Which would⊠make it difficult to see anything on an ultrasound as well?" he fills in.
Momentarily, your eyes lose their focus, staring into nothing but the air. "Realistically, they should still be soft enough to ultrasound 'cause, you know⊠they're not solid, but that bad boy over there is getting up there in age," you nod toward the ultrasound machine. "The portable one is with Yoongi, who's on call."
Jeongguk hums, dark eyes watching you and patiently waiting for your decision.
A thought hits you.
"Would youâ" you start, gesturing toward the exam table before you have time to really consider whether your spontaneous idea will help or not. Unbothered, Jeongguk returns to his seated spot.
You approach, looking at his arm (entirely professional this time). You're curious about his muscles, and well, the arm he used to lift the car with is as good as any.
"Do you mind if I�" you reach carefully for him.
He shakes his head, lifting his arm slightly toward you. You grasp it by the elbow as you consider where to start. God, it never stops surprising you how warm he is.
"Okay, relax," you mumble.
Besides warm like a radiator, his arm is so incredibly heavy, almost to the point where you lose your grip on it when he obeys your request and lets it go limp. Adjusting the hand under his elbow for support, you move the other to the inside of that same joint. All the while, you feel his curious gaze on you as you get to work.
"Not sore?" you ask, referring to how you just stuck a needle into that same spot.
"No. What are you searching for?" he asks, eyes on your fingers as you work them as gently as you can into the crease of his elbow.
"Your distal biceps tendon. Can you do this for me real quick? Make a fist and flex your arm, just a small bend at the elbow?"
He copies your brief demonstration, the contrast between your flexed arms almost comical. Still, it works, and you feel the tendon pop out under your thumb, its thickness and strength very obvious. The question is only: to what extent?
Using both hands again, you move one up his semi-flexed, very impressive biceps, and you try your best to trace the underlying anatomy, your eyes focused on the wall behind him. He's⊠firm. That's the best way you can describe him. Warm and firm.
"Can I fold this up?" you ask, tugging a little on the sleeve of his t-shirt in order to get to his shoulder.
"Yeah. Or I can justâ?"
You take a step back when he grabs the shirt by the back of his neck and yanks it off.
"Yeah. Or that," you smile, trying not to stare at his golden chest. He just has to have your absolutely favorite body type, doesn't he? Wide shoulders, overall muscular but without too much, stringy definition. And that itty-bitty waist, complete with two tiny skin rolls as he sits? Not to mention the veins, but those practically never leave your mind anyway, spanning his hands and running all the way up his shoulders, even. And that's just his body; his face is even more gorgeous.
Oblivious to your infatuated thoughtsâor maybe not, but you're not even going to consider thatâhe puts the shirt beside him, once more offering you his arm.
"Flexed? Or relaxed?"
"Relaxed. I'm just trying to locate some of your tendons and see if, for any reason, I wouldn't be able to ultrasound them."
"What would that reason be?"
"Not sure," you shrug, putting your hands back on his upper arm. "Maybe they're covered by super dense muscle? Maybe you have bone-plated armor covering weak spots like the crease of your elbows? Actually, nevermind; I wouldn't have been able to draw your blood if that were the case, but you get my point."
He grins, amused, eyes focused on your hands again as you start to move them, feeling the top of his shoulder.
"The two biceps heads go here," you explain, pressing your thumb near the front of his shoulder joint and your middle finger just a bit higher and inward. "Should be able to see them on the ultrasound as well. And the muscle, itself⊠It's definitely soft when relaxed," you murmur, running both hands down his relaxed arm again, palpating the thick tissue.
"While you have your shirt off⊠Can I..?" Slowly, you let go of his arm, pointing to his side.
"Yeah, go ahead. Whatever you want."
You laugh quietly at his complete compliance. "I appreciate it. Your sacrifice for science."
He chuckles too, moving his arm out of the way as you pull the chair closer with your foot again, sitting down. With your right hand, you feel his side, where multiple layers of muscle cover his ribs.
"I heard your heart better from here, and⊠while your serratus anterior is quite dense and strongâyeah, I can barely feel your ribs under these musclesâthose are probably the real problem," you nod toward his pecs. "But I think I'll be able to see your heart as well, unless there's an internal aspect causing issues. If I can get a probe between your ribs, that is."
"Between them?" he lifts an eyebrow.
"I'm not gonna jam something between them or anything," you're quick to explain, placing two fingers against his side, in the space between two ribs. "I'll put the probe here in an intercostal space, against your skin, and hopefully the sound waves make it between the ribs."
"Hm," he leans back on his arms, and you remove your hand from his skin. "Well, you're welcome to try whatever you want."
Why does he always have to say things like that? Why?! Simply pretending like he said something that didn't make your chest warm, you offer a grateful smile and stand up.
The ultrasound machine squeaks as you roll it over to where you want it, positioning it next to the exam table.
"Do I lie down? People lie down for these, don't they?"
Walking over to the light switches, you flick one of the two main ceiling lights off. "You can, but it might not be very comfortableâ"
Turning, you see him already flat on his back, his lower legs hanging freely off the edge and toward the floor.
"It's not so bad," he comments, earnestly.
"Heart this way, though, please," you smile as you approach, even more so when he sits up to lie the other way.
"Is there a reason you turned the lights off? Or just for coziness?"
You laugh. As if youâtrying so hard to be professional in the most unprofessional situation everâwould turn the lights off for 'coziness.'
"It makes it easier to see the screen. These old screens aren't as powerful as the new ones."
Spending a moment in silence going through the probes available, you then settle for one and reach for the gel on the little tray.
"This can be a little cold," you warn, squeezing an appropriate amount onto the probe.
He doesn't say anything, his eyes focused on the ceiling.
"I'll start with your heart," you add, sitting down and adjusting the long white cable attached to the probe.
But then you realize that his arm is in the way. "Could you⊠put your arm either above or under your head?"
"Sure," he agrees calmly, lifting his arm and putting his hand under his head. It gives you a whole new angle of not only his thick and defined arm but his side and abdomen as well. Naturally, your eyes do a quick scan. There's a dark tuft of hair growing in his armpit, something you find unreasonably attractive.
Jeongguk doesn't react when you put the gelled-up probe to his pec. Using your left hand to angle it against his skin, you push the old, worn-down buttons on the machine's small desk with your right, trying to find not only the best angles but also settings.
You mutter your slight frustration when the display merely shows a foggy outline of a mass. Even though this particular machine still performs well enough on animals, it might just have met its match in Jeongguk's pectorals.
"Try to relax as much as possible for me, okay?" you say, eyes locked onto the screen as you hope a slightly softer muscle will be easier to see through.
It doesn't work though, and you're forced to give up. But only after another few minutes of double checking angles and settings, of course; you don't admit defeat that easily.
Jeongguk lets you work in silence. It's comfortable and calm, not awkward in the slightest. He breathes slowly and evenly, taking the odd deep breath when you ask him again to please do his best to relax as much as possible.
Moving the probe to his abdomen, right below the junction of his ribs as you try to tilt it up and underneath them, you spot something.
"Well, your liver looks rather⊠normal," you state quietly, watching the organ show up on screen like that of any human. At least as far as you know; you don't do ultrasounds on humans, but there shouldn't be that much of a difference.
"Ohâand there's your heart."
Jeongguk turns his head, and the movement has you losing the angle. "Wait. Hold on, lie still; I'll show you."
He keeps his head turned, his eyes warming your face as you adjust the probe, trying to find the image again. It takes you a few seconds, and then you feel yourself light up.
"Look," you say, carefully turning the machine to face him while trying not to move the probe. "It's not the best image, and it's from below, but there it is."
It's fascinating, the small, grainy glimpse of the powerful organ that graces the screen. It beats just like you've heard it, slowly, every contraction precise. Even watching it, a sense of calm washes over you. There's no rush; it does what it's done since long before you were born and what it will continue to do for however long Jeongguk lives. Another few centuries? Millennia?
"Cool."
You chuckle. Jeongguk grins youthfully when you meet his gaze. Of course, he's not as impressed by his own heart, maybe more so the technology that actually lets him see it.
"Yeah. And even though the image is kinda⊠meh, look here," you trace the faint outline of the heart wall with your finger. "See how thick it is?"
"UhâŠ" he watches but doesn't seem to quite understand your fascination.
"Okay, hold on," you say, removing the probe from him, and with a little more gel on the top of it, you grab the lower hem of your shirt and move the probe underneath. It doesn't take you nearly as long to find the corresponding angle on yourselfâyour abs aren't made of steelâŠâand there it is, only sharper and clearer.
"Do you see the difference? The walls of your heartâthe muscle itselfâare much thicker than mine," you trace the same shape on your own visualized heart; almost pathetically small compared to Jeongguk's. Not only that, but it beats fast, contracting quickly as if you're in the middle of a marathon. The contrast is almost absurd.
"Yeah," he smiles. "Seems like you're excited about something?"
You huff and remove the probe from your skin, watching the screen go dark. "Mean. And here I was going to show you my condition."
He tilts his head, his curiosity having lost that teasing edge, the tone bordering on worried. "You have a condition?"
"Kinda."
"Well, show me."
You give him the sternest look you can muster.
"I'll be nice, I promise."
"Fine."
Luckily, the shirt you chose to wear today is of the looser, boxier kind, allowing you to slide the probe back under it and against your side. You breathe slowly, trying to calm your heart at least a fraction.
Jeongguk sits up, dark eyes glued to the sight of your beating heart. It thumps evenlyâif only faster than hisâuntil it doesn't.
"Wait, that beat was much quicker?"
"Yeah."
"Is that not⊠dangerous?"
"Keep looking."
He returns his focus to the screen, watching intently. "It happened again. Your rhythm isn't even like mine."
"No. I have 'regular irregularities,'" you explain softly. "It's not dangerous since the rhythm doesn't deviate. Or at least from what's normal for me. It's more like a little quirk."
He bites his lip, and, for a long second, looks at you.
"Can I feel?"
"Feel?"
"Your pulse."
"Uh," you start, more surprised than unwilling. "Sure."
Before you know it, he's reaching his large hand out, gently grasping your neckâthe back of it, at leastâand with his thumb on your artery, immediately finds your pulse. You guess that's maybe even more of his expertise than it is yours, so you don't bother reminding him that it's generally best to feel for someone's pulse with a finger other than the thumb, which has its own pulse, easily confused with the subject's.
You try desperately to calm your poor heart, willing yourself to breathe slowly as every thump beats against his thumb.
"Relax," he mumbles.
"Be niceâ"
"I didn't imply anything," he defends. "I think I have yet to meet even one human whose heart doesn't race when a vampire feels for their pulse. It's instinctual."
Maybe also because you're hot, you almost want to say.
It's only because he's staring into the air as he feels your pulse that you manage to lower it even slightly. A moment passes. And then another; the room enveloped in a thick silence, Jeongguk's warm hand still around the back of your neck, and his thumb on your carotid artery.
"Interesting. I'm not⊠new to wacky heartbeats, but I don't think I've ever felt one that's⊠regularly irregular."
He lets go of your neck, and you look at him. "Well, do you listen often? To someone who's not scared you'll eat them?"
"No, not really. Not that I eat humans, cause I don'tâyou saw the powdered blood I useâI just don't really listen to heartbeats," he explains, which has you nearly rolling your eyes. It's sweet, how he still really doesn't want you to misinterpret him. "Do you feel anything? Is it noticeable?"
"No, I don't feel it," you answer. "I've probably always had it. It's just the rhythm my heart has."
He hums, accepting your answer before he lowers his gaze to the probe in your hand. "âŠYou're not done with me, are you?"
You grin. "No."
Admitting defeat with a smile of his own, he lies back down. You reach for the gel again, turning the screen back.
"Arm up, please."
He lifts his arm and tucks his hand under his head again. This time, you touch the probe to his side, trying to find another view of his heart.
Just like you hoped, a few moments of quiet searching later, and you have the clearest side view of his heart yet. The resolution still leaves quite a lot to be desired, but you're grateful nonetheless, your fingers tapping the buttons to activate the color Doppler mode.
"Do you want to see more? How your heart moves your blood?" you ask, smiling brightly but realizing that far from everyone is as nerdy as you.
"Sure," he answers. Having learned from last time, he doesn't move a muscle, instead waiting patiently for you to turn the screen toward him.
"So, this setting visualizes the blood flow as colors; red is the blood coming toward the probe. Blue is the blood going away from it."
"That's interesting."
"You think so?" you ask. You wouldn't be surprised if he's mostly pretending to be polite.
"I mean, yeah? It doesn't really tell me much, but it's fascinating to see. And I can tell that it makes you happy."
You turn the screen back, eyes locked onto his grainy, slightly foggy heart. With every slow beat, a portion of the screen lights up in red, then blue. You think that's when another realization hits you; not one that douses you in ice water, whispering that you're prey in the presence of a predator, but a calm excitement that⊠you found something. You found something amazing, something out of this world, and for all you know, you're one of few to ever have a heart like this under your ultrasound probe.
Calm yet powerful like nothing else, his heart moves what must be an immense amount of blood with every contraction.
"Have you ever had your blood pressure taken?" you mumble, pressing another button on the control pad.
"No. It's the tube that goes around your arm, right?"
Nodding, you turn your head to watch him. Or more specifically, his arm. "I'd love to measure yours," you admit almost longingly. "But we don't have any cuffs here that would fit you. We typically measure a horse's blood pressure around the base of their tail, so that's just a human cuff, but it's in the field bag with Yoongi. The canine cuffs we have here won't even clear your forearm."
"Well, if you find a wayâŠ" he says, still watching you with that calm, slightly curious look.
You return your attention to the screen, taking the chance to see Jeongguk's heart from every angle possible.
Ultrasonography is a skill learned through time and experience: lots of it. Still doesn't mean it's easy for you or that you can just slide the probe around willy-nilly and find what you're looking for simply because you've got hundreds of them under your belt. You need a light yet stable hand and the knowledge of where to go. Also a bit of luck.
"Do you need me conscious?" Jeongguk's low voice asks after a few more minutes. "Cause I might fall asleep."
"It's that boring?" You look at him, endeared and smiling. "Wait. You sleep?"
You're not sure why you're so surprised, staring at him like he just told you he can levitate. It would be exponentially weirder if he didn't sleep; it just never crossed your mind that he would. He chuckles.
"Yeah. It's not boring, it's just that I'm lying down, in a quiet and dark room. That⊠touch is pretty soothing, and you keep ordering me to relax."
You try not to blush, removing the probe from his skin and looking around for the tissues to remove the gel. "Do you want to stop? Or at least continue another day?"
"No. I don't mind," he yawns. "Continue. Test me, stick me, feel me up; I don't mind."
You pause, forehead creasing. "While you sleep?"
"Yeah? Just a warning, I sleep pretty heavily. If you need me awake, just⊠shake me. I'll wake up sooner or later."
"Okay," you snicker. That is such an apex predator advantage. No one is going to eat you, so why bother be on guard?
Not even five minutes later, he's out; his eyes closed and his breaths slow and even. Not entirely satisfied, you're still looking at the blood flow from his heart on the monitor, moving the probe around ever so slightly.
When you were in university, your class got to visit a zoo. The on-staff veterinarian demonstrated how they sedate their animalsâlarge predators, mostlyâby dart, and then they opened the enclosures and let you all inside. You particularly remember the lion, who they suspected had torn a ligament, and the brown bear requiring dental work.
It's a feeling like no other, working on a sleeping predatorâthe sleeping bear, quite literallyâand with your elevated heartbeat, hoping to God they don't wake up before you're done and safely outside.
Working on Jeongguk while he sleeps feels similar in ways you can't really explain. While he's not a 200 kg lion, he's huge, lying on the table in front of you with his legs hanging down. And even if you're not actually scared that he'll wake up because you don't think he'll eat you, it's there regardless; the deep, subconscious knowledge that everything he lets you do to him, even if it's essentially whatever you want, is on his terms and his terms alone.
So while the smallest change in Jeongguk's breathing doesn't scare you shitless like the tiny groan the lion let out as you touched its paw, you're still aware of it.
Twenty minutes later, when you suspect you've seen everything the machine can show you of his heart, you carefully wipe the gel from his chest and move toward his abdomen. The moment you put the probe to his skin again, you wait, eyes on his face and awaiting a reaction of some kind, but there's nothing.
Considering his words of consent, you continue, moving the probe around to locate his organs. In humans and most animals, the intestines are alwaysâto some extentânoisy. Food, liquid, and gas are constantly processed by the interior muscles, and it creates a steady background hum of activity. But from what you can see of Jeongguk's abdomen, it's entirely silent and still.
You see the organs relatively clearly through his abdominal muscles, whichâdespite being thick and surely strong as hellâaren't quite as dense as his pecs. And his organs are there; blood is circulating to and through them; they're justâŠdormant.
But as you glide the probe over to where his bladder should be, you don't find it. Only on the third pass do you spot it, appearing entirely empty and therefore tiny. It confirms what he said about his near-perfect closed-loop system, where his kidneys don't really output urine unless to get rid of excess fluid.
Quietly amazed, you wipe the gel from his abdomen and some stray streaks that you previously missed on his chest.
Your next target is his arm, but before you do anything else, you quietly stand from the chair, softly padding out of the exam room to pay the locker room a quick visit. Considering everything Jeongguk is doing for you and your curiosity, you can at least make it as comfortable as possible for him. That's the reasoning behind bringing him your personal pillow, carefully putting a hand under his head to slide the pillow in under it.
Just like the lion's paw, Jeongguk's limp arm isâbesides warmâincredibly heavy. Struggling a little more than you care to admit, you maneuver it to hang off the edge of the table and into your lap, where his body heat radiates straight through your clothes.
Holding onto that big, heavy, veiny arm, you touch the probe to his biceps, and what you find is so, so interesting. While his heart looked a tad bit bigger than that of a regular man his size, it appeared disproportionately strong, the muscle responsible for its contractions dense and thick, almost like his pecs.
Similarly, the muscles in his arm show up bright on screen, so dense that you barely see through them. It explains perfectly why he's quite a bit heavier than he appears.
You don't rush, feeling alright about taking your time since Jeongguk is sleeping either way. Besides the muscle bellies themselves, you spend quite a while inspecting the different tendons in his arm. As well as you can, at least.
Where the tendons are exposed, like the biceps tendon on the inside of his elbow, they're thick and bright on screen. Clear and sharp. But where they disappear in under too much overlaying muscle, they blur as the soundwaves scatter. You can't conclude much more than that they're thicker than a human's, but you felt that even when you palpated him earlier.
The biggest discovery, however, is probably when you move the probe to the inside of Jeongguk's biceps and over his brachial artery. It's the arm's main blood supply, and it should be well-developed for any relatively fit and strong man. In fact, its size shouldn't be that much of a surprise when you can feel the outline of Jeongguk's even while he sleeps.
But the moment the artery is centered under the probe, and you see the on-screen numbers measure the diameter to be 5.6 millimeters wide, you blink in shock. Almost dropping the probe, you scramble to dig your phone out of your pocket and open the browser, searching for the average brachial diameter for a human man.
3-4 millimeters. Ish. Apparently, an exceptionally strong climber measured at 4.4 millimeters and attributed his almost superhuman strength to his wide arteries. And Jeongguk's is 5.6 millimeters.
His arm rests limply in your lap as you note the numbers down on a nearby stray piece of paper, underlining it twice, as if you'd possibly forget. That has to be one of the big explanations, right? For his super strength? His muscles and tendons are disproportionately strong on their own, yes, but they can generate so much more force and for so much longer because his body can provide them with an almost endless supply of oxygen.
God, now all you need to know is what the hell is in his blood. With that additional puzzle piece, you feel like you're one step closer to solving the mystery that is his strength.
When your own heart finally calms down from the discovery-induced adrenaline high, you find yourself simply watching the flow of his blood for a few minutes. For some reason, it's very soothing, like watching waves hit the shore on an empty beach.
Before you turn off the machine and clear Jeongguk's skin of the remaining gel, the last thing you do is adjust the settings to also thoroughly inspect the uppermost level. His skin.
As expected, and aligning with what you've already seen, it is noticeably thicker. There's not much fat, but the skin itself is thick. You reach for the pen again, writing down a question.
'Sensitivity?'
You power the machine off, the absence of the low humming suddenly making the room almost eerily quiet. Jeongguk is still fast asleep, his handsome face so youthful. You smile to yourself; he wasn't lying when he said that he was a heavy sleeper. Still, you don't watch his face for too long, for some reason convinced that he, at any second, will open his eyes and stare at you. You don't know what you find scarier: him suddenly and unceremoniously staring at you, or finding you staring at him.
Pushing the ultrasound cart away slightly, you settle back into your chair again, carefully grasping his arm. It's one thing to see something on screenâpretty badly portrayed, at thatâit's another to feel it. In your line of work, your patients can sometimes show you what's wrong, even if they can't outright tell you. But they can also be entirely stoic or just simply unreliable, and so you've learned to rely a lot on your hands, feeling for whatever's not right.
Rolling your chair just a tad closer, still with his hand in your lap, you run your hands softly up to his shoulder, planning to get a better feel than the previous preview. Throwing a quick glance at his face, you confirm that he hasn't reacted.
You start by tracing your fingers over his shoulder cap, feeling exactly where the thick muscle fibers anchor onto his collar bone. Lifting one hand from his skin, you trace the same part on yourself just to compare. While your attachments are distinctly human; still relatively strong but with a certain degree of "give," Jeongguk's feel much harder. It makes sense because, as established, a muscle can't be stronger than its bone attachments allow it to be.
Returning your hand to his shoulder, you slide your fingers down a little further, carefully prodding the inside of his armpit for the lymph nodes.
There's a sound.
Almost like a quick exhale of air. Your gaze snaps to Jeongguk's face, but he hasn't moved a muscle, still entirely quiet and relaxed. You must've imagined it, or it was the ultrasound machine finally powering down completely. Old things like that make random sounds, after all.
You let your hands move again. Just like the lymph nodes in his neck, the nodes in his armpit are harder than normal, for a human at least.
Continuing further down, your hands reach his biceps and triceps. You've seen the thickness of his upper arm before, even had your hands on him briefly earlier tonight, but it's another thing to really get to feel. You won't deny that palpating the dense muscles makes your heart skip maybe an extra beat, but you'd absolutely keep that fact to yourself. Besides increasing the inevitable attraction you feel toward him, the curious scientist in you is thrilled.
Jeongguk's biceps is incredibly well developed, no surprise there, but you're almost surprised at just how dense his triceps is. Additionally, as you prod the muscles, eyes unfocused on the wall, you note that there's basically no intramuscular fat, or at least you can't feel any. You continue to trace the three heads of the triceps, mapping where they anchor to the elbow.
Concluding that, yeah, he's got a physique rather similar to human men, just leveled up and engineered to withstand more forceâlike⊠a lot moreâyou slide one of your hands down to his wrist, grasping it and lifting.
Struggling just a little, you move his heavy lower arm slowly back and forth, folding it at the elbow, just to get a glimpse of his range of motion. You think perhaps it's a little greater than what's considered normal in a human, but flexibility in humans is highly individual. It could be for vampires as well? You wouldn't call his range of motion unnatural, at least.
With that out of the way, you continue your descent, feeling for the elbow's attachments in the other direction, toward his forearm. They feel just as strong, no surprise there. With your left hand, you feel for the right spot in the middle of his forearm, carefully digging your thumb into the flesh. There's not a lot of give, and it takes a quite a lot of pressure, but then you see it; how his middle finger twitches. Moving your thumb a little to the side and pressing, you get the index finger to react, too.
His wrist is thick and so are the veins running on both sides of it. Actually, all sides of it. You lift his hand again, gently rolling his wrist to test the range of motion of that joint as well. There's zero friction, no sounds or jumps, just fluid motion.
The results remain consistent when you move on to feel the muscles in his hand and his fingers, very gently stretching and curling them. Your own wrist pops occasionallyâsomething it's always doneâa reminder that you, at least, are human.
"What are you feeling for?"
The low voice breaks the silence just as you're done with his pinky. It startles you, and your wide eyes flit to his face to find his dark eyes watching you.
"God, don't scare me like that," you complain, exhaling. But you also feel your cheeks heat. His voice didn't sound⊠newly awoken. "How long have you been awake?"
"Uh, since you started feeling me up," he grins lazily.
"I wasn't feeling you up," you defend, groaning internally. You've been 'feeling him up' for way too long. "Why didn't you tell me?"
"Don't worry, I said that you could, didn't I?" he continues, and you can tell he doesn't mind. "And it felt nice; I didn't want you to stop."
You roll your eyes, cheeks very warm.
"So did you learn anything?"
You nod, excitement overriding your embarrassment because you did. "Yeah. So, in conclusion: your muscles are dense. So much so that it does make it more difficult to see past them on the ultrasound. And probably why it was a little harder to hear your heart as well. Your heart is a little bit bigger than what I'd consider normal in a human man, but it works roughly the same, only stronger and capable of moving more blood around. Your brachial artery, however," you say, lightly tapping the spot on his inner biceps. "Is insane."
Jeongguk lifts his eyebrows and sits up, stretching briefly. "How is it insane?"
"The average brachial diameter for a human man is around 3 to 4 millimeters; some peaking at roughly 4.5. Yours is not only thick and extra muscular, but it's 5.6 millimeters in diameter; that's a lot. Logically, that would mean that not only is your heart pumping a lot of blood around, but your veins and arteries are better equipped to deliver that blood to your muscles. And to your other organs, of course."
Jeongguk listens intently, quietly curious, as you continue.
"So not only are your muscles denser, your heart bigger, and your veins and arteries thicker to handle the added pressure, your tendons are crazy thick as well. If they weren't, you'd probably risk tearing the muscles from your bones with how strong you are. You also seem to have a slightly wider range of motion? I don't know if that is a vampire thing or a you thing? For humans, it varies a lot, even among those that don't have connective tissue disorders like Ehlers-Danlos."
"Never thought about it."
You shrug. "Then it's probably not a big deal. The movement of your joints, at least your elbow, wrist, and fingers, is very smooth. No clicking or incongruence."
"Like you have?"
"You noticed that?"
He smiles and nods. Then he tilts his head. "What⊠was it that you did when you pressed on my forearm?"
"I was feeling the tendons that control your fingers. Seeing if I could manipulate them."
"My fingers?"
"Mhm. Look," you say, holding your hand out.
Jeongguk fulfills your request, holding out his forearm and watching as you trace his warm skin to find the spot again. "Relax your hand. Hold on. Okay, see?"
With your thumb pressing down, his middle finger moves, curling slightly.
"Oh? That's cool."
"Yeah. A bit of a party trick," you grin, letting go of his arm and leaning back. "Oh, almost forgot. Your abdomen is very⊠quiet. Not a lot going on there as you probably knew. And your bladder is practically entirely empty, which supports what you said about your mostly 'closed loop' system."
"Yeah. That, I knew," he smiles widely.
With your cheeks burning yet again, you reach for his shirt, handing it to him. "Thanks for⊠letting me do all of this."
Telling yourself that it's not weird to be fascinated by him and his anatomy doesn't make you feel any less of a perv, unfortunately.
"No problem. If this is how it is going to the doctor, I kinda wish I could go too."
You laugh. "This is not how it is at the doctor's. And if it is, you need to report the doctor."
"Why?" he smiles, and fuck, you dug a grave and stepped right in.
Why? Because it's inappropriate?
"Well⊠for one, I'd say we're⊠friends? I don't have the responsibility to treat you for something like a doctor would for their patient. I'm actually not even a doctor; I'm a vet, and the way I work is a bit different than how a doctor would with human patients."
"You go by touch?"
"Yeah. I use my hands to evaluate a lot. Besides, you're not a human, and you shouldn't be asleep at the doctor's."
He puts the shirt back on, amused.
A thought hits you. "You don't have any doctors of your own? Vampire doctors?"
It's still odd to say the word out loud.
"We do, but not a lot since we rarely need them. We have a few different⊠services, but they're more like caretakers. Like, if someone gets poisoned or actually dehydrated, they can help take care of them. Quite a few vampires live in solidarity, so it can be hard to survive things like that if you don't have anyone to take care of you."
"Oh."
"Yeah."
"Those friends you were with, at the bar that night?"
"Also vampires," he grins. "They're not from around here but TaeâTaehyungâis thinking of renting a house here for a few months."
"Really?"
"Yeah."
It makes you wonderâŠ
"There aren't any other vampires here. At least not right now," he says, clearly having realized your train of thought and met you at the station.
"Oh."
He tilts his head. "Are you relieved?"
You think about it. "Uh⊠I don't know? I guess that makes the chances of being killed by something supernatural⊠lower, but⊠I mean, you're nice."
He laughs, lifting his arm to look at his watch. "Oh, shit. I have to go."
"You have⊠plans? At ass o'clock?"
"Uh⊠yeah. Vampire plans," he starts, eyes however widening slightly at his own words. "âŠThat definitely do not involve hunting humans for food."
It's your turn to laugh. Does he sound like a bad liar? A bit, but it sounds more to you like he just wants to make sure you're not getting the wrong idea and trips a little over his words in the process.
"Okay. Have fun? And, uh, thank you again for⊠you know, letting me do all of this."
He grins. "Anytime. Text me when you're home."
Your cheeks get no break tonight, it seems. Still, you nod as you watch him throw the jacket back on as well.
You drive home, falling asleep right after putting his blood in the fridge. And you dream about his warm body and dark eyes. And it hits you as you wake up, that you weren't scared. Nervous and... aware, sure, because you inevitably like the very handsome and charming vampire, but even as he joked about his vampire plans, you were never truly scared.
