Plot

Hanabi Ayase and her best friend, Yui Aoi, are 6th graders in school. When Hanabi is chosen to work with Yuuto Takao for an upcoming test, she begins to fall in love with him and they both start dating. Yui also falls in love with Kazuma Hiyama, after he protects her from a classmate who talked about Yui behind her back, and they start dating as well.

Characters

Main characters

Hanabi Ayase (綾瀬花日, Ayase Hanabi)^[3]: Voiced by: Ai Kakuma^[6]; 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: Nanami Haruno (OVA); Juri Kimura (TV series); 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)^[6]: Voiced by: Sōma Saitō^[6]; 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: Yūichi Iguchi (OVA/game); Shun Horie (TV series); 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.

Supporting characters

Marin Ogura (小倉まりん, Ogura Marin): Voiced by: Mayuki Makiguchi; Hanabi and Yui's best friend and makes up the three-girl clique along with them. She thinks that boys her age are immature but helps her friends during their love troubles normally by acting like a love adviser, conveying the wisdom of her unseen elder sister, who has apparently had several boyfriends.
Cocoa Hamana (浜名心愛, Hamana Kokoa)^[6]: Voiced by: Sayuri Hara^[6]; Cocoa is Hanabi's love rival for Yuuto. She does everything to become his girlfriend, including dishonest and ungainly means. In front of people, she acts sweet and innocent, but acts mean to make Hanabi lose her self-esteem and confidence.
Ayumu Tsutsumi (堤歩, Tsutsumi Ayumu): Voiced by: Tetsuya Kakihara; Hanabi's childhood friend who has just come back from Tokyo. He also wants to be her boyfriend.
Eikou (エイコー, Eikō): Voiced by: Takumi Watanabe; Eikou is one of the biggest pranksters in Class 6-2. He teases girls, makes girls' popularity rankings (which winner is usually Cocoa) and collects Yuuto's "golden thoughts".
Tomoya (トモヤ): Voiced by: Taishi Murata; Tomoya is one of the biggest pranksters in Class 6-2. He teases girls, makes girls' popularity rankings (which winner is usually Cocoa) and collects Yuuto's "golden thoughts".
Inaba Mikami (三上稲葉, Mikami Inaba): Voiced by: Atsushi Tamaru (game); Shinnosuke Tachibana (TV series); Inaba is a fellow student from Yui's cram school who took an interest in Yui after hearing that she had a boyfriend.
