Yoh Komiyama

A high school senior of Haruna's who is a year older than her. He knows the ways to impress men from a girl's point of view. Thus, he becomes Haruna's coach to make her more popular among guys.

Despite being known as a hottie and being popular among girls, he does not acknowledge this fact. He is quite embarrassed about his popularity. He gets shy easily especially when he is praised.

During his childhood days, he was a difficult child. He never smiled in photographs. He does not like to be the centre of attention. Apart from that, he is cold and does not talk much.
