When an introverted male student meets a girl called Nagatoro, his life is turned upside down. She first quietly observes his reaction to verbal abuse from some other high-school girls that are not well-meaning, realizes that oddly enough in his case it may be exactly what he needs, and so begins a sequence of her teasing him.



Who Is Hayase Nagatoro (長瀞 早瀬)?
Nagatoro is a 15-year-old girl who likes to mess with Senpai and finds joy in teasing him. Although it appears that she just wants to torture him, it is progressively confirmed that she actually has a crush on him. Whenever anyone else tries to bully her Senpai, she becomes very hostile towards them. Her friends call her "Hayacchi" (ハヤっち) and seem to sometimes be an annoyance to her.
