Y/n mistakenly befriends a yandere. A yandere who is totally straight and stalking some poor girl by the name of Miho. And so, Y/n stalks the stalker... (just to make sure things don't get too out of hand.) Their second year, however, changes the game. A transfer student notices the conservative, relatively friendless Y/n, and in turn a certain yandere best friend notices too... (Written in third person.) *Mature*

[Male x Male] Y/n L/n is the most infamous resident of Rosemary Sanitarium, an inpatient hospital for the violently insane. He went to trial for five murders, pled the insanity defense, and now sits in glass box for doctors gawk at day in and day out. However, no one seems to be able to decipher this stoic boy's behavior. No one is able to answer the near decade-old question of why he killed those people in the first place. So, Y/n entertains doctor after doctor, each one eventually giving up. ...Until the day one doesn't.

(Male!Yandere x Male!Reader) Y/n has no idea how to navigate through the treacherous (but somehow completely undefined) relationship he now has with his yandere best friend. Akihiko is hot and cold. Murderous in one moment and indifferent in the next. Then Y/n catches someone's eye.

Y/n L/n is now at the mercy of Kisaku. He spends his days chained in a dank basement. A sliver of window is his only light. But really, is the room any darker than this psychopath's mind? Y/n L/n plots, Kisaku falls further down his rabbit hole, and the police fan out in search of the sanitarium's infamous escapee. Where oh where will it all end up, I wonder.
