Good Girl and Delinquent

Everyone in class fears Ai. She’s always covering her face with a mask, wears a Hannya jacket, and hardly speaks a word to anyone. She must be a delinquent! Two of her classmates are told to give Ai her homework handout but are too scared to approach her. Luckily for them, the class representative - Watanabe - offers to do it in their stead. Little do they know that Ai is a gentle soul, and that their class rep is the actual delinquent!
