In his first year of high school, making friends is not so easy for Shota Raido.

Characters
Reina Aharen (阿波連 れいな)
An expressionless female high school student who is talented in many fields, such as cooking and arts. She becomes Raido's girlfriend. In her third year of high school, she wants to attend an arts school in another prefecture. She marries Shōta at the end of the series.
Shōta Raidō (来堂 章太)
An expressionless male high school student with a tendency to overthink. He becomes Aharen's boyfriend. He is aware that he has a scary face, which led to him not being able to make friends during junior high. However, despite his face, he is a kind and considerate person who puts his family and friends above himself. After graduation, he becomes a novelist and participates in an expedition to Mars.
Mitsuki Ōshiro (大城 みつき)
A tall high school girl who used to be in the same class as Reina and Riku during her elementary school years. Initially wary of Shota due to his scary face, she soon opens up to him after Reina tells her Raido's good points. She is very skilled in martial arts, hiding, surveillance, and beauty care. Her parents own a barbershop.
Ms. Tōbaru (桃原先生)
A classical Japanese literature teacher who is also the main characters' homeroom teacher during their second year. She has a habit of getting a nosebleed whenever she looks at the Raido-Aharen couple because she sees them as "wholesome". She is best friends with Miyahira-sensei and usually spends much free time with her.
Ishikawa (石川)
Raido's classmate and friend, also Hanako's childhood friend. He is very popular among his peers, though he has an inferiority complex that causes him to be distant from Hanako. He calls Hanako "Hana-chan".
Hanako Satō (佐藤 ハナコ)
Raido's classmate and friend, also Ishikawa's childhood friend. She is concerned about the distance between her and Ishikawa.
Ms. Miyahira (宮平先生)
A PE teacher and the main characters' homeroom teacher during their first-year. She is best friends with Tōbaru-sensei but is concerned with her gluttony whenever they eat out together.
Raido's Little Sister (ライドウ妹)
A middle school student who’s friends with Eru. Despite her somewhat cold attitude towards her brother, she actually cares a lot for him.
Atsushi (あつし)
A neighborhood boy who worships the Aharen siblings and believes that they are talented in sports and games, which may not necessarily be true. He, along with his friends, always badgers the Aharen siblings to teach them new games or play with them.
Futaba (ふたば)
Atsushi's friend who is in love with him. She mistakenly believes the entire Aharen family to be her enemy because they are trying to steal Atsushi away from her. She is a tsundere to everyone, not just to Atsushi.
Ren Aharen (阿波連 れん)
Reina's younger brother who is in elementary school. He likes dressing up as his sister, though this habit causes many misunderstandings among the characters.
Eru Aharen (阿波連 える)
Reina's younger sister who is in junior high school. She is also friends with Raido's little sister, though ironically she is hostile towards Raido himself. This hostility is because Eru believes she cannot be Reina's number one and is always relying on her big sister. Though, over time, she seems to soften towards Raido when he continuously demonstrates his kindness towards everyone.
Ai Aharen (阿波連 あい)
Reina's mother. She approves of her daughter’s relationship with Raido. She cares about her children a lot, and stops them from doing dangerous things. However, she herself tends to bite more than she can chew when she wants to try something new, such as skateboarding or card games.
Riku Tamanaha (玉那覇 りく)
A gyaru transfer student who appears during the main characters' second year. Despite her appearances, she is a shy and introverted girl who just wants to make lasting friendships. She was also Reina and Mitsuki's classmate in elementary school, though she does not remember Mitsuki in particular because her family moved around many times.
Ms. Henzan (平安山先生)
An English teacher and the main characters' homeroom teacher in their final year of high school. She is a new teacher with a passion for education and uses the government curriculum guidelines to deal with the Shota-Reina couple, whom she mistakenly believes to be delinquents. Her notable feature is her double tooth.
Takashi (たかし)
An elementary school student despite his gakuran, flashy hairstyle, and delinquent manner of speaking. After losing a duel to Shota in a park when Ren is playing, Takashi worships him as his "Master". He is actually a kind boy who follows rules and plays with his friends normally.
