SENIOR.
[ yandere! villain x upperclassman! reader ]
summary: after reincarnating into your favorite otome game. you found yourself in the body of the selfless upperclassman of the main characters. determined to change the destiny of the characters, especially the obsessive villain who suffers in every route. you decided to take this matter in your hand. but spoiler alert, it changed your supposedly quiet school life. congratulations!
so you died. as simple as that. how did you die you ask? well, let's say that you experienced the good ol' truck-kun that every isekai-d character experienced before they found themselves on other worlds.
and now, after getting hit by a car you found yourself under a certain beautiful man. hurriedly getting up, ignoring the fact that your head was bleeding— you immediately asked him if he was alright. only for him to throw back the same question and that's how you fainted at the sight of your own blood on your hand when you touched your wound.
that's how you acquired your memories on your past life. you immediately recognized the man earlier. that's calyx white, the obsessive villain on your favorite otome game before.
the main reason why you liked that otome game was the fact that there's no villainess. the crown prince (one of the male leads) has no fiancee or whatsoever. and besides, the design of the characters was superb. you're on your way to buy the second version of that game when you died by the way.
so, waking up in the infirmary. you found calyx on the chair beside your bed. quietly reading a book. seeing you're finally awake, he suddenly gave you a money and said that you shouldn't do it again because he was more capable to protect himself.
oh gosh. he was really cranky and looks like a lone wolf! that's how you and calyx became acquaintances.
on every routes of the game. calyx always ends up dying because of the heroine when the only thing that he wanted was affection and attention from someone. you hated it. why would the heroine always ends up choosing the playboy (crown prince), muscle brain (upperclassman) and pedo (the teacher) anyway?! when she had this adorable guy wanting her attention?!
but honestly, unknown to you. this guy wasn't adorable at all. because he was more darker than you expected. you haven't realized that the reality you were currently in was different from the game that you played in the past.
but did you care? no.
instead, you started your "give calyx a happy ending!" plan.
first, you started by greeting him every morning. acting like a friend and a proper upperclassman. you honestly doesn't have any plans to be his significant other, don't worry. you're just doing this to make sure that he will stay alive this time. you're not going to let your adorable junior die!
unbeknownst to you, he noticed your little efforts. but did he care at all? no. yet, he found himself looking forward on your small greetings and silly ways to make him smile.
calyx have always known to be the problem child of the ducal family. everyone avoided him because of his appearance (when the truth is he is too fucking handsome) that's why he grew up wanting affection and attention from others.
and who is the first person who gave it to him? the heroine. that's how he became addicted to it and started following the heroine around.
as a yandere, calyx was obsessive, manipulative and controlling. he wanted the heroine around him all the time. to the point that in the bad ending of every routes, he always locked up the heroine on his family estate and kill all the male leads.
but right now? calyx attention was diverted to you, his stupid yet selfless upperclassman.
at first, he was cautious. he thought that you only wanted the trust of his family when you protected him when the two of you fell from the stair. then, he became curious, why are you starting to act as if the two of you were friends?
he didn't trust you at first. i mean, why would he? when everyone want him dead?
but during one of the events in the otome game where calyx were accused killing one of the students in the campus (even though it was really the last boss) you were the only one who believed him. hell, you even told everyone that you were with him when they asked where he was the time the crime happened.
that's how you turned the cautious calyx into a more calm one. he started greeting you back and agreeing to spend more time with you.
you were able to change him, congratulations!
and on the last event of the otome game. where everyone supposed to condemned calyx for his evil doings. he apologized, which surprised everyone. even the crown prince who supposed to be calyx's childhood friend was surprised. what the hell? when did calyx learnt the word sorry?
you, who was celebrating the fact that calyx didn't die in this route. didn't even notice how calyx was now standing in front of you.
“eh?”
you blinked rapidly while calyx smiled. it was different from his usual lazy one. instead it was twisted, unhinged even. very fitting on his role as the obsessive villain in the otome game.
you change calyx? no, you're wrong. you only diverted his obsession from the heroine to you.
congratulations, (name)! now, you've got yourself a yandere junior who is willing to set the empire in fire if you want to.
oh, by the way— there would be a high chance that he will force you to marry him or lock you up in a castle if you did something like making him jealous or saying that you don't like him.
so be careful with your words, okay?
“ just give into me and i will give the world, senior. ”
