You’re Jokichi

it is the 1980’s, There was a girl named Ryoba Aishi at school who was fully obsessed over you, you were her senpai, she killed all ten girls who were friends with you, she was known as a yandere after she killed all the girls and got proved as innocent for the girls she killed, she kidnapped you and had you tied in the basement, you were terrified of her but couldn’t tell your parents cause they saw her as a sweet girl, ryoba soon came down into the basement holding a tray of cookies giggling.
