Mainly a male character because there's only Yato X Fem Reader

INSANE ASYLUM

Yato had no idea why (Y/N) was in the asylum. He was more sane than everyone else, only humming to himself or fiddling. He wasn't like the others and trying to find a way to escape. In fact, no one else knew why either. One day, he kind of just, showed up.

He was really happy, but it wasn't annoyingly like some of the others. Yato had checked all documents of his, but none of them listed why. (Y/N) would either sleep or talk to people who came in. He wasn't even bothered by the fact he was constantly in a padded white room.

So, one day, Yato decided to ask him.

It was like any other day at first. Yato would bring him breakfast, talk for a minute or two, leave, watch him eat and hum tunes, and repeat for lunch. Dinner was different how ever.

Yato sat down this time, smiling so much it looked fake. "So, (Y/N), how did you end up here?"

"What? I thought you already knew by now? You've been here since my first day, surely you're aware?" (Y/N) seemed more confused then usual.

"Actually, I've looked around for why. I can't find a single thing." He chuckled, scratching his head.

"Oh, well, you'll find out one day." He smiled.

And that's how Yato began looking everywhere for an answer.

He checked if any of his relatives were alive. All of them were dead. Most died from suicide or old age. Both his parents were arrested though.

Most of his exes or friends were dead or all the way across the world. Yato barely had any money, so it was kind of hard to take planes.

The only other person was a certain ex. He was in the asylum when she broke up with him. Her name was Nora or something. Sadly, she had filed a restraining order against (Y/N), and if Yato said that he was a pleasant person, she would slam the door on him.

Yato was so confused. There wasn't a single document with why or even a newspaper article (not that he looked at more than one.).

He slammed his face on the table, groaning loudly. He heard a girl's giggle, who put a hand on his back. "It's Hiyori. You've been nervous all week, is something up?"

Yato glanced up, popping up, "Y-Yup! I'm fine, it's just a small problem."

"Is it about what (Y/N) did to get here? I'm not completely sure, but I do have an idea." Hiyori said.

Yato's eyes lit up, "Seriously? Please tell me, I've been looking for weeks!" He regained his composure, "Oh, uh, right. I'd like to know."

"It has something to do with murder. Nora, or whatever her name was, filed a restraining order on him because of him murdering her family." Hiyori explained, making Yato taken aback.

"That can't be true! He's a really sweet-"

"Go ahead and ask him if you don't believe me. He'll probably tell you."

"So, why did you murder your girlfriend's parents?" Yato said, playing with his jeans and looking anywhere but at (Y/N).

"Oh... So you found out? Well, Nora never had time for me, and honestly, I got jealous." (Y/N) said, gripping his sleeves. "I know you don't want to be near me any more, I understand."

"I... No! As long as you don't hurt me, it's alright." Yato grinned, patting (Y/N) on the head.

"Aw~, thanks, I haven't heard someone say that in a while. Then again, I haven't talked to anyone but you and a few doctors." He chuckled, biting into a strawberry.

"Right, well, that shouldn't land you in here though, but in jail. Is there more people you killed? I won't leave, not matter how many." Yato tilted his head, tucking his hair behind his ear.

"Well... I don't know. Last I remember it was twenty-nine. Most were her exes, two were her parents, and five were perverts she met in bars." (Y/N) mumbled, hoping Yato wouldn't ask anything else.

"So you ended up here for being a yandere? You seriously loved her that much?" Yato questioned.

"I don't even know why. Nora cheated on me, she didn't love me that much." He rolled his eyes.

Yato had a sad smile on his face, "Hey, I won't be leaving you, even after you leave the asylum."

"Really?" (Y/N) said.

Yato nodded, holding out his pinky with a dumb smirk on his face. (Y/N) smiled, interlocking pinkies.

"Alright, you better not be lying." Yato squeezed the other.
