Heyy!! I was wondering if you could do a L x reader where the reader gets killed by Kira because they were involved with L. If you aren’t confortable writing this it’s ok! Thank you~
Hello Anon and thank you for the request!! I'm comfortable with it and even though I'd rather see L being happy, I am a sucker for angst. So hopefully I do this justice!
Also note I have rewritten this way too many times to count 😭 I really tried my best, but I'm so sorry this took so long! Also there was technically two requests asking for the same sort of thing. I’ll get to the next headcanons as soon as I can, but hope whoever is reading this had a great day/night wherever you are!
CW: Death, angst, fluff, kind of long
It was yet another normal day for the genius detective who called himself L. He had spent a majority of the day working with the task force members on the Kira case, mainly in monitoring the cameras inside the task force headquarters as well. It wasn't just the task force and Watari he was working with though, he also had the person he called his partner, in both work and romantically.
Being in a relationship was obviously nothing he sought out or even bothered thinking about as he grew up, mainly finding himself way too focused with his work. He never thought of himself as someone to ever be with someone romantically and it was something he didn't feel sad about, he just didn't see the point in such a matter and didn't have the time for it. Yet that all changed when you entered his life.
You were something he never expected. You came in and even though he may have tried to ignore you or treat you as he would with any person he would meet, you were different. You had met him years before the Kira case and made it clear that you simply wished to be by his side no matter what. Something he never understood, but never doubted as you had proven to him time and time again how loyal you were and that no matter the challenge, you would conquer them together.
So he has asked you to work with him behind the scenes and you accepted. It seemed to have worked out very well too, as you had remained at his side unknown to the rest of the world just how he planned. It seemed like no case could do anything to knock either of you down, and L had even asked for you to move in with him. It was great, and it felt like you two could handle anything together.
Then Kira came to be.
L didn't want you to get involved at first, but once again your stubborn nature would prevail.
"If you have to risk your life by going to Japan, I will do the same. I will not stand by and let you do this alone!"
It was one of the things you said, and it was the main thing that stood out to him and at that point he knew you wouldn't back down. So he agreed, letting you join him and Watari in going to Japan to help with the Kira case.
L snapped out of any thoughts he had when his lover moved up from where they laid, getting into a sitting position and resting their head against his arm gently.
"Is something the matter?" He found himself asking, raising a brow as he glanced over at them.
"Of course not, me wanting to be close to you isn't a bad thing" they would chuckle, moving a bit closer to the detective as he couldn't really argue with that.
"I can tell there's a lot on your mind though, and I wish I could do more than just let you get lost in your work." His partner would frown as their gaze looked up at him a bit more.
L would stare at them for a couple moments, it wasn't surprising that they'd take notice of his behavior after all. If it wasn't Watari catching on to how he might be feeling, it was his darling instead.
"Well I'd rather get as much done with the Kira Case as possible… but if you had to decide on what I should do instead, what would it be?" He'd respond in his usual calm manner, wondering to see how they'd respond and it seems they knew right away.
"Easy, I'd want you to take a break."
"You know that could be a bad ide-" he would start but you quickly cut him off.
"It's never a bad idea to take some time to take care of yourself and recharge, so when you go back to working you'll feel even better." They must have been thinking of this for a while with how fast they knew how to react to his statements.
"I appreciate the thought Y/N, but-" He would begin, but they'd simply shake their head as they turned so they were sitting on their knees facing them.
"I've already discussed this with Watari, and even he agreed a small break could be beneficial for you and the case. It won't be long, maybe a day at least or something.. like tomorrow for example."
Of course Watari would go on their side, what a traitor, but honestly a small break didn't sound too awful.
"Hm.. what would I even do on this break?" Inquired the messy haired man.
"I was thinking that me and you could just spend some time together and do whatever we want that doesn't deal with the case…" his partner would begin to say, looking up at him with an almost longing sort of way. "It's been awhile since we've been able to do that sort of thing."
"... That is true." L paused for a few moments, his work centered mind battling the other half that wanted to spend as much time as possible with the person he loved. "I have missed spending more time with you like that.."
Y/N would give him a soft smile as they scooted closer, moving his laptop slightly off to the side of his knees as they tested their hand on top of them instead.
"So is that a yes to the break for tomorrow?" They'd ask, leaning up a bit towards L who at this point had moved the laptop off of his lap completely and to the side of the bed so he could have his focus on them.
"Mhm, it seems you know what's best for me after all" he'd say with a soft chuckle as his lips curled up into a soft smile.
His lover's eyes would light up as their smile widened as they moved closer, putting L's knees down so they weren't too close to his chest.
"I'd like to say so at least" they'd say in a playful and low tone as they moved as close as they could without being on his lap.
Their face soon being inches away from his own to the point they felt each other's breaths mingle together. Soon enough the space between them disappeared as they couldn't hold back and kissed the dark haired detective. It was soft and warm before they found themselves deepening it, as if showing how much they both longed to just be together. L would bring a hand up to cup their cheek gently as they kissed for what he wished could last longer, but they pulled away after a couple of moments.
His partner's gaze remained on his face, chuckling softly as they leaned in and hugged him tightly. L would accept it as they ended up on his lap so he could hold them better. He rested a hand on their back as his other ran through their hair gently.
"I can't wait for tomorrow" they'd say in an excited whisper, causing him to chuckle.
"I can't wait either, I can already tell it's going to be more than worth it." L would say in an almost purr as he rested his eyes, them both snuggling together more, enjoying the closeness and warmth.
"I love you." His partner would say softly, their chin resting on him and their voice sounding as if they were getting ready to drift away into a nice sleep in his arms.
"I... you too..." He would reply a little hesitantly as he rubbed their back gently, listening to their heartbeat and steady breathing as their grip remained around him. The word love was something he had trouble with saying, as it was something he wasn't sure if he fully understood, but even if he couldn't say the word just yet, Y/N understood and seemed content nonetheless.
They would continue to enjoy their silence together, it was peaceful and just felt perfect. A great way to end a day and get ready for the day they looked forward to together. L wasn't someone who looked forward to the days to come too much as he had his focus on work to the point where he'd lose track of time, but when it came to Y/N, he felt like he could truly experience normalcy for once. He had so much to look forward to, even if he wasn't really sure what that was yet. It felt like a fairytale he read once, where even through the rough times the two love interests would get through it together to have their happy ending.
Unfortunately, this wasn't a fairytale.
After what must have been around 5-10 minutes, when L had found himself beginning to drift off himself something changed. Something he could have predicted, but with the circumstances this was something he hoped would just never happen throughout the case, something he had tried to prevent with all of his safety precautions. It seemed as if he hadn't done enough though.
The grip from his partner's would suddenly tighten as their heart rate would increase and their breathing hitched, making them let out a gasp. L jumped a little at their actions, his eyes shooting open as he turned his gaze towards them.
"Y/N?? What's wrong?" He'd ask immediately, looking at them as their grip on them began to loosen more and more as their head slumped down as if they were on the verge of falling asleep still.
L didn't know why at first but he felt dread creep up on him as his heartbeat began to race. Then he remembered people like Lind L Tailor who had a similar reaction, right before he.. no. No. His mind felt like it was beginning to buzz as he kept denying that possibility, repeating his partner's name as he raised their head to look at him.
Their gaze wasn't anything like earlier. The light and all the warmth they had, how L could tell how they felt with a simple look, was gone. It seemed almost glazed over, distant, and any form of light was gone and dull as they stared up at him.
Many questions went through the man's mind, how did Kira find out about them? How did they find out their name?? Did he know their connection to him?? What went wrong??? Yet his thoughts were torn from the questions as his dearest would groan softly in pain. They still could react which meant this wasn't some ordinary heart attack like Kira's last victims, perhaps there was a way to save them.
"Y/N?? I know you can hear me, please say something-" L would begin but he knew that if Kira had gotten to them that his time was limited and that he had to act fast. He moved over to his phone, pressing a button that would contact Watari or any of the task force members.
"Watari!" L began, his usual calm tone beginning to show some sort of panic as he spoke into the device, demanding that the older man or any of the members get in her to help. He didn't have much time to say a lot, just saying that you were hurt as needed medical attention as soon as possible. He didn't want to even bring up the name of the bastard that he knew was behind it, simply because a part of him didn't want to believe it even though it was obvious.
After talking into the device he turned his full attention back onto the person that meant most to him who laid in his arms, their struggled breathing quickly becoming steady but more faint as the minutes passed. They stared up towards him with their lost gaze.
"Hold on, Y/N, help is coming.. Just hold on, It'll be okay." L began as he took their hand as all they could do was simply stare at him.
As they stared and seemed to be struggling against what was happening, their breathing was becoming more faint as tears began to form at their eyes. It seemed that they were unable to speak, every time they opened their mouth to speak, a look of pain washed over them.
"Keep holding on, it'll be okay Y/N.. just keep holding on for me." He tried his best to keep his voice calm, yet as he looked down at them he felt his voice beginning to shake as if he was going to break.
The fact they haven't died yet felt cruel to the man who held his lover, as if Kira was doing this on purpose somehow. As if they didn't deserve the mercy of having a quick and painless death in comparison to last criminals. This was a way for Kira to get back at L directly, and it was working unfortunately.
L frowned, wiping their tears with one hand quickly before he checked their pulse. It was slowing down. No.. no, this can't be happening. This had to be some sort of cruel nightmare, something that wasn't unusual for him, but he knew that wasn't the case here. Watari soon arrived in the room with Soichiro and the other members, who looked like they wanted to help yet as Watari went over to L and Y/N, they had a feeling that there wasn't much they could do anyways.
As the pulse began to slow down and their breathing began to sound more forced as they struggled to speak and breathe normally, but under the influence of Kira it was impossible. There wasn't much time left, Watari knew this and so did L. They all knew that the fate of Y/N was in the hands of Kira and he had chosen to make their last moments something for the others involved to remember, as if it was a warning.
L watched their expression as Watari tried to do what he could to keep her awake, which wasn't a whole lot unfortunately. His hand was still on their pulse as it slowed down even more. L couldn't stand this. He kept speaking to Y/N, no.. at this point it was more of a plea. Begging for them to keep going, yet as he saw how much they were suffering he wondered if it would be better if Kira could just end their suffering once and for all, which hurt him to even think about in the first place as he still was in denial about the situation.
It couldn't end like this. He had promised to keep them safe, but he had failed them. Yet they had a peaceful look on their face as they smiled, as if they had accepted it. They began to open their mouth again, and even though they couldn't actually speak it was easy for L to see what they were mouthing. It was them saying that they loved him, and the more he thought about it, it seemed as if this was what they were trying to say this whole time.
"I.. I love you too…" He found himself finally saying. The phrase he struggled saying fully and the one time he can actually say it was when they were being taken away from him. What type of cruel joke was this?
His lover's eyes began to close, the smile on their face beginning to slowly fade. He held them close, fighting back any sort of emotion as he could hear their heart beginning to beat slower and slower.. until it finally stopped completely.
"She's gone." Was all Watari said softly, mainly to the other members who had remained silent.
The shock of the situation had made it hard for any of them to react, not sure what to say or do, especially when it came to L who went dead silent. It was as if they were all trying to figure out what to do next, but no one seemed to know the answer at that moment.
What happened afterwards was a blur for L as he held them close, all he remembered was Watari announcing it in the room and the rest of the world around him became fuzzy. The person who was teaching him how to love and loved him full heartedly, the one person who he had let in to see a side of L that no one else dared to bother with, was now gone. Kira had taken them away from him.
He didn't know how it happened, yet he knew it had to be his fault. If he had been more careful, they would have most likely been fast asleep together to prepare for their break the next day. His chest ached as if he himself was having a heart attack of some sort, and a part of him would have preferred that then the pain that seemed to consume him. He kept his face down and buried into his partner's shoulder for who knows how long in the silent room.
He wasn't sure what to do or say as the loss began to wash over the room. Matsuda looked as if he wanted to go over and comfort him, but even he knew that wasn't the best course of action. So the task force members kept their space, just remaining silent as Watari sat close. After a few moments the older man had waved towards the door, meaning it would be best for them to leave. So they did, leaving L alone with Watari. Soichiro would get in contact with someone to handle Y/N, but they'd all be respectful as L took this time to process everything.
Watari rested a gentle hand on his shoulder, something L didn't react to at first before he looked up and glanced at Watari, tears had managed to fill his eyes. A sight that wasn't common to say the least. He looked at Watari, as if asking his caretaker what to do next but he gained no answer. Instead Watari just sat beside him with his hand on him gently, a small gesture yet it was something the detective needed.
~~~
About an hour later, Y/N was taken away and L was left staring blankly out a window. The atmosphere was heavy as the task members haven't said too much to L yet, and when they did it was them apologizing for the loss and trying to show that they cared and were there for him. L didn't respond though, avoiding their gazes almost completely and stayed to himself for the most part. As he stood by himself by the window, Matsuda would find himself walking over finally.
"Ryuzaki…" he'd begin, making his presence known and to see if there was a response but not surprisingly there wasn't.
"Is there anything we can do tonight?" He asked, frowning as he looked at his feet a little for a few seconds. "Whether it's something for the case or to help you feel better-"
"No." L had finally spoken, cutting off the other male who looked up a bit in surprise.
"Huh? What do you mean no?"
"There's nothing we can do at the moment for the case, and there's only one thing that could make me feel better about this situation."
"What is that?" Matsuda asked, yet even he had a feeling what the answer could be. So it didn't surprise him hearing it.
"Simple. Catching Kira."
