Synopsis: When Heeseung's older brother leaves his almost-two-year-old son in the care of the newlyweds for three weeks, Heeseung expects chaos, sleepless nights, and survival mode. What he doesn't expect is discovering he's surprisingly good at bedtime stories, getting jealous of the toddler stealing all of his wife's attention, and imagining a future that suddenly doesn't seem so far away.

The first thing Lee Heeseung learned about babysitting was that toddlers had more energy than grown adults.

The second thing he learned was that his nearly two-year-old nephew could somehow fit an entire toy dinosaur into his mouth while simultaneously trying to climb a couch.

And the third thing?

His wife looked unfairly adorable taking care of children.

"Yah, Minjun!" Heeseung rushed across the living room, gently pulling the plastic dinosaur away from the little boy.

Minjun blinked up at him with wide, innocent eyes, then immediately grabbed another toy.

"How is he this fast?" Heeseung asked.

From the kitchen, Y/N laughed. "Auntie experience."

"You babysat your cousins a few times. That's not experience."

"It absolutely is."

Their nephew let out a delighted squeal before running away—well, toddler-running, which mostly looked like an excited penguin wobble.

Heeseung stared. Then he looked at his wife. Then back at Minjun. Then at his wife again.

Y/N noticed. "What?"

"Nothing."

"You're staring."

"I'm observing."

"That's staring."

Heeseung smiled sheepishly. Seven months into marriage, and he still got caught every time.

Three weeks.

That was how long Heeseung's older brother and sister-in-law would be away for work.

His brother, Minho, and his wife, Soojin, had looked almost guilty while dropping their son off.

"Are you sure?" Soojin had asked.

"Absolutely not," Heeseung replied honestly.

Y/N smacked his arm. "We'll be fine."

Now, forty-eight hours later, Y/N was indeed fine. Heeseung, however, was hanging on by a thread.

Since both worked remotely, they had converted their home office into a temporary, toddler-safe zone complete with baby gates, foam mats, tiny books, and stuffed animals. Yet, somehow, the tiny human still found ways to cause trouble.

"Where did he get the spoon?" Heeseung asked.

Y/N looked up from her laptop. Minjun was proudly holding a wooden spoon. Nobody knew where he'd found it.

"Maybe babies just spawn with random objects."

"That sounds right."

Despite the chaos, something surprised Heeseung: he liked it. A lot.

Especially watching Y/N. He loved the way she crouched down to Minjun's eye level when talking to him, the way she never got frustrated when he repeated the same thing twenty times, and the way she celebrated every tiny achievement like it was a Nobel Prize.

"Look!"

Minjun stacked two blocks. Y/N gasped dramatically. "No way! That's amazing!"

Minjun giggled, and Heeseung completely melted.

Later that afternoon, while Minjun napped, Heeseung found Y/N curled up on the couch answering emails. He sat beside her, and his head immediately landed on her shoulder.

"Tired?" she asked.

"A little."

"You survived today."

"Barely."

She laughed. "You did good."

"I lost him for thirty seconds."

"He was under the dining table."

"Exactly."

Y/N reached up and played with his hair—a habit she'd developed after marriage, and one Heeseung secretly loved.

"You know," he murmured.

"Hm?"

"You're really good with kids."

She smiled softly. "I've just been around them."

"No," he said, turning toward her. "You're gentle."

Her cheeks turned pink. "You make it sound special."

"It is."

For a moment, neither spoke. The apartment felt peaceful, warm, and comfortable. Like home.

Then, a tiny cry echoed from the baby monitor. Nap time was over.

Y/N groaned. Heeseung groaned louder.

The next challenge arrived at bedtime.

Minjun refused to sleep. Passionately. The little boy sat in bed looking personally offended by the concept of rest.

"He gets this from your side," Y/N whispered.

"My side?"

"Look at you."

"I sleep."

"At 3 AM."

"That's still sleeping."

She rolled her eyes, and Minjun giggled. Traitor.

After another failed attempt, Y/N finally sighed. "Maybe tell him a story."

"What story?"

"Any story."

"I don't know stories."

"You read books."

"That's different."

She shoved him gently toward the toddler bed. "Go."

Heeseung sat down, and Minjun looked at him expectantly. Y/N watched fondly from the doorway.

"Okay..." Heeseung cleared his throat. "There was once a brave dinosaur."

Minjun's eyes widened. Good start.

"The dinosaur wanted cookies."

Y/N covered her mouth, already laughing.

"So he traveled across Cookie Mountain."

The story made absolutely no sense. There were talking ducks, flying sandwiches, a heroic turtle, and a cookie kingdom. By the end, Heeseung had invented an entire fantasy universe.

And somehow, Minjun was fast asleep.

Y/N stared in disbelief. "What?" Heeseung asked.

"Heeseung."

"What?"

"That was amazing."

"It was complete nonsense."

"It worked, didn't it?"

He looked down at his sleeping nephew. A tiny hand was still clutching his finger, and something warm settled deep in his chest. "Oh."

The following week brought many discoveries. Heeseung learned how to make dinosaur-shaped pancakes, how to clean spilled juice in under thirty seconds, how to identify different cries, and how to distract a toddler from a tantrum using a sock puppet.

Most importantly, he learned he genuinely enjoyed taking care of Minjun.

One afternoon, Minjun tripped while running. It wasn't a serious fall, just enough to scare him, but tears immediately welled up in his eyes. Before Y/N could even move, Heeseung scooped him up.

"Hey, hey, it's okay."

With tiny sniffles and a trembling lower lip, Minjun buried his face into Heeseung's shoulder. The crying slowly stopped.

Y/N watched quietly, her heart swelling. Heeseung looked so natural—protective, patient, and gentle. A future she hadn't expected to picture so clearly suddenly appeared right in front of her.

Apparently, Heeseung was thinking the same thing, because later that night, after Minjun was asleep, they sat together on the balcony with warm tea under the city lights.

"He likes you a lot," Y/N said into the comfortable silence.

Heeseung smiled. "I like him too."

A pause settled over them before he spoke up again. "Do you ever think about it?"

She glanced at him. "About what?"

"You know..." His ears turned a bright pink. "Future stuff."

Y/N smiled immediately. "Future stuff?"

"Our future." The blush spread down to his neck. It was incredibly cute.

She reached for his hand, intertwining her fingers with his. "I do."

Neither rushed the conversation, and neither pressured the other. It was just two newlyweds sharing their dreams.

"When the time's right," Y/N said softly.

Heeseung nodded. "When the time's right." Then he grinned. "But hopefully ours won't try eating dinosaurs."

"No promises."

By the end of the third week, Minho and Soojin finally returned.

The reunion was emotional. Minjun immediately ran to his parents, then ran back to Y/N, then to Heeseung, and then back to his parents again, completely unable to decide who he missed most.

Everyone laughed at the display.

"You survived," Minho said, patting his brother's back.

"I deserve a medal," Heeseung replied. "A trophy. A parade, even."

Soojin smiled warmly. "Thank you. Seriously."

Y/N shook her head. "We loved having him."

And they really had. The apartment felt strangely quiet after Minjun left—no tiny footsteps, no scattered toys, and no random wooden spoons appearing out of nowhere.

That evening, Heeseung wandered into the living room where Y/N was folding laundry. He wrapped his arms around her waist from behind, resting his chin on her shoulder.

"The house feels empty," he murmured.

"A little."

For a moment, neither moved, just enjoying each other's presence. Then Y/N smiled. "You're going to miss him."

"I am."

"You got attached."

Heeseung sighed dramatically. "He stole my heart."

"Along with all of my attention."

"Exactly."

Y/N laughed. "There it is."

"There what is?"

"The jealous husband."

Heeseung buried his face in the crook of her neck. "I suffered."

"You survived."

"Barely."

She turned around in his arms and kissed his cheek. His expression softened instantly.

"Still," he admitted quietly, looking at her with the kind of smile reserved only for home, for family, and for her. "I think someday we're going to be really good parents."

Y/N's eyes softened. "I think so too."

Standing there in their cozy apartment, wrapped in each other's arms, Heeseung couldn't help but feel excited for whatever future waited for them. Whenever that future came, there was no rush. There was only love, and a home already full of it.

i'm not drawing verse 2. leave it to people who draw anything spicier than hugs and pecks...

the song will be below

No one warns you what it’s like to become an aunt overnight to not one, not two, but four kids at the same time. You think you’re signing up for the occasional birthday party, maybe babysitting once in a while, a cute drawing stuck to your fridge. Instead, you find yourself knee-deep in chaos, laughter, and at least one child trying to eat dog poop. (Yes, really. That happened. And no, I’ll never emotionally recover from it.)

Meet my squad: Claire and Rose, my boyfriend’s sister’s kids, and Mary and John Frank, my boyfriend’s brother’s kids. Together, they are four tiny hurricanes with sticky fingers, big personalities, and an unshakable belief that I’m both their favorite playmate and a grown-up responsible enough to stop them from burning the house down. Spoiler: I am neither.

Claire: The Mischief Queen

Claire is what you’d call a hands-on learner. She doesn’t believe in the phrase “don’t touch that.” She believes in experimenting. She once ate dog poop just to see what it tasted like. (For the record, I did not encourage this science experiment, nor do I recommend it.) Another time, she figured out how to turn the stove on all by herself. Nothing says “instant heart attack” like seeing a toddler casually twisting a burner knob while humming to herself like she’s in a Disney movie.

Claire is the definition of a wild child—equal parts mischief and charm, with a will that could bend steel if she set her mind to it. She has this fearless streak that keeps everyone on their toes, whether she’s sneaking snacks like a tiny bandit or testing the laws of gravity by climbing anything taller than she is. Her humor comes naturally—those mischievous grins, the dramatic giggles after pulling off some stunt—and even when she’s driving you half mad, she somehow makes you laugh in the middle of it. Claire doesn’t just live life loudly, she charges at it headfirst, with all the energy of a toddler who has absolutely no intention of slowing down.

Rose: The Foodie Comedian

Rose is my spirit animal. This girl has two settings: ignoring everything you say, or eating with such commitment that you wonder if she’s in training for a hot dog–eating contest. She’s the type of kid who, when you tell her “no more snacks,” will look you dead in the eye while simultaneously sneaking goldfish crackers into her mouth.

She’s effortlessly hilarious—the kind of kid who can make you laugh when you’re trying your hardest to be serious. If Claire is chaos, Rose is comedy. She’ll ignore every rule with a straight face, then do something so absurd you can’t help but crack up. How are you supposed to stay stern when the same child who just launched LEGOs across the room is now twirling around the kitchen, holding a granola bar like it’s her microphone and she’s headlining a sold-out show? With Rose, even the mischief comes with a punchline.

---

Mary: The Quiet Genius

Mary is the brains of the operation. She’s sharp, observant, and always watching. You can almost see the gears turning in her head as she calculates the best way to get what she wants. She’s like a tiny CEO with a clipboard. If you tell her no, she won’t throw a tantrum—she’ll circle back in ten minutes with a PowerPoint presentation of why you’re wrong.

Spending time with Mary feels less like babysitting and more like being interviewed for a job you didn’t know you applied for. She’ll just look at you like, “And what qualifies you to be our aunt?” And honestly? She’s not wrong.

Mary also has a way of making you feel like you’re part of her grand plan—even if you’re not sure what that plan actually is. She’ll hand you a toy, give you a look, and suddenly you realize you’ve been drafted into some elaborate scheme she’s orchestrating. She doesn’t just play house; she runs it. And somehow, you’re always reporting to her

---

John Frank: The Thinker

Then there’s John Frank. He’s smart like Mary, but quieter about it. He’s the type of kid who will sit back, let the chaos unfold, and then calmly say something so insightful it makes the adults in the room stop and stare. Like, “Did you know dinosaurs probably had feathers?” And you’re just standing there holding a juice box, wondering why you suddenly feel like you need to go back to school.

John Frank is also the most likely to remind you that kids are always paying attention, even when you think they aren’t. He’ll repeat something you said three weeks ago word-for-word, which is both impressive and terrifying.

John Frank also has this way of observing the world that feels older than his years. He’ll watch everything play out, take it all in, and then drop a thought so perfectly timed it feels like wisdom disguised in a kid’s voice. It’s never loud or showy, just simple and true. Being around him reminds you that sometimes the softest presence can carry the most weight.

Me: The Fun Aunt (and the “What Have I Done?” Aunt)

Somehow, in the middle of this four-child circus, I’ve earned the title of fun aunt. I’m the one who sneaks them extra snacks, laughs at the jokes their parents would roll their eyes at, and lets them dance on the couch when we’re supposed to be “winding down.” I’m also the one who gets tackled the second I walk in the door. There’s no such thing as a casual entrance when four kids are sprinting at you like linebackers.

But I’m also the what have I gotten myself into aunt. The one who lies in bed at night wondering how four people under the age of ten managed to completely outsmart me, again. The one who thinks babysitting will be “chill” and then ends up Googling “how to get slime out of hair” at 11 p.m.

It’s a strange balance, being the aunt who wants to say yes to all the fun but also knows that yes sometimes leads to Claire cooking the family dog.

The Chaos is the Point

Here’s the thing: as much as I joke about the chaos, the truth is—I wouldn’t trade it. Being an aunt to four wild kids at once is exhausting, hilarious, terrifying, and heart-melting all rolled into one. It’s the sound of giggles echoing through the house, the little arms wrapping around your neck, the sticky kisses you swore you didn’t want but secretly love.

It’s Claire’s mischief, Rose’s laughter, Mary’s sharp questions, and John Frank’s quiet wisdom. It’s being the person who isn’t quite a parent but isn’t just a random adult either. It’s finding out that love can look like holding sticky hands, answering a million “why” questions, and laughing until your stomach hurts because Rose just announced she wants to marry pizza.

Yes, they’re wild. Yes, they’re exhausting. But they’re also four of the best reasons I’ve ever had to show up, to laugh more, and to find joy in the chaos.

Birthday Wish #3

‎I just got a call from my uncle. It still feels so fucking weird talking to myself on the phone. But shit… turns out this body swap is only gonna last 10 days. My uncle admitted he’s the one who did it, he got a wizard to switch our bodies because he wanted to relive his youth again.

‎I only have a few hours left before we switch back. Fuck it, I need to take as many pictures of this body as possible for my collection. What pose should I do next? Should I record myself jerking off with my uncle’s body too?

Lunar Eclipse through telescope in Texas, March 3, 2026.
