Main characters[edit]

Hanabi Ayase (綾瀬 花日, Ayase Hanabi)[2]
Voiced by: Ai Kakuma (OVA/anime)[7]
Hanabi is the first protagonist of the series along with Yui and is part of a three-girl clique with Yui and Marin. She is very child-like from her appearance to her behaviour, with her two signature pigtails and innocent charm that makes her oblivious to the boys' actions in class unless it is very obvious. She gets close to Yuuto during a music session when their homeroom teacher required them to partner with the classmate they are sitting beside, which happened to be him. Initially oblivious towards his feelings for her, she finally develops feelings for him when they share their first kiss. She has a bit of a one-sided rivalry with Cocoa, who is the most popular girl in class and wants to be Yuuto's girlfriend as she believes them to be a perfect couple.
Yui Aoi (蒼井 結衣, Aoi Yui)
Voiced by: Juri Kimura (anime); Nanami Haruno (OVA)
Yui is the second protagonist of the series along with Hanabi and is part of a three-girl clique along with Hanabi and Marin. She is developing both physically and mentally the earliest out of the group, but is still insecure due to the presence of not having a mother around to help, so she often asks Marin. Projecting a model student air, Yui initially dislikes Hiyama due to his delinquent-like attitude and his hobby of teasing her, but grew to like him after he spent a long time trying to find something important for her that she lost.
Yuuto Takao (高尾 優斗, Takao Yūto)[7]
Voiced by: Sōma Saitō (OVA/anime)[7]
Yuuto is Hanabi's boyfriend and is very affectionate of her. He is the most popular boy in school, and that is matched with his good looks and mature appearance that makes almost all the girls, especially Cocoa, fawn over him. He develops feelings for Hanabi early in the story and kisses her on the rooftop. They start going out and become Class 6-2's first actual couple.
Kazuma Hiyama (桧山 一翔, Hiyama Kazuma)
Voiced by: Shun Horie (anime); Yūichi Iguchi (OVA)
Kazuma starts off as a delinquent-like prankster and a rash speaker, but actually has a soft side to him. Having a crush on Yui early in the series, he covers it up by teasing her and leading a group of three boys to do foolish antics to rile her, but stopped soon after. He helps Yui find a precious item that she lost and confesses when she does so too. They start going out and become Class 6-2's second couple after Hanabi and Yuuto.
