Perverto is just a regular 17-year-old...with the unavoidable nickname, ?pervert.? Unlike his namesake, he's actually quite na?ve when it comes to sexual matters, his first and only youthful romance having ended terribly. To escape his bad reputation, he transfers to a new school for a fresh start. But on his first day there, he's falsely accused of groping a girl named Hongdan on the subway. To make matters worse, she happens to be another new student who has just transferred to his new school, to his very class. The real pervert who framed him is a math teacher at his new school, too! The teacher is an expert at getting away with perverted behavior...and he's targeted Hongdan for more gropes. The girl possesses a voluptuous body and mysterious bruises, and Perverto is smitten with her. But when Hongdan expresses her romantic interest in him out of the blue, Perverto is reminded of the hurtful memories of his first love and runs away screaming. Will he survive his new school?
