He was shunned by everyone around him, especially by the girls, who called him a "creepy guy" and hated him.

She is the leader of a group of girls who bully the main character. She and the main character have been childhood friends at the same school since they were small children and were reasonably close as children, but she became aggressive toward men after a certain incident. Later, she became the center of the girls' group because of her charisma, and she and her cronies began to bully the protagonist. Her parents, a top trading company man and a famous cookery expert, raised her with a laissez-faire attitude, so she grew up starved for affection. Although she appears to be a playful young woman, she has never had any experience with men.

♀ f

A dark and shy classmate and one of Rei's cronies. She is a quiet girl with a plain, petite figure. She is naturally inclined to be bullied, and has had such experiences in the past, but thanks to the fact that she is liked by Rei, a member of the girls' group, she has been able to get protection.

A dark and shy classmate and one of Rei's cronies. She is a quiet girl with a plain, petite figure. She is naturally inclined to be bullied, and has had such experiences in the past, but thanks to the fact that she is liked by Rei, a member of the girls' group, she has been able to get protection. Perhaps because of this, she has no initiative to adapt to others and rarely asserts herself in a situation. Perhaps because she is mentally unstable due to her involvement in this incident, she is at the mercy of the protagonist.
