When 30-year-old Daikichi returns home for his grandfather's funeral he learns about the existence of Rin, his grandfather's illegitimate six-year-old daughter by an unknown mother. The girl is an embarrassment to all his relatives and is treated as an outcast. Annoyed by their attitude, Daikichi decides to take care of Rin himself, even though he is single and has no experience raising a child. As Rin becomes part of his life, Daikichi experiences the hardship of a single parent. He is befriended by the single mother of Kouki Nitani, a friend Rin meets in nursery school, who gives him advice on raising Rin. After a year has passed, Daikichi acknowledges his sacrifices for Rin have been worth it. The first half of the series focuses on Daikichi's perspective and struggles raising Rin. Ten years later, Rin is a high-school student and the remainder of the series focuses on her trying to figure out how to deal with her feelings for Kouki, and her decision for a career. Rin discovers that she has no family ties to Daikichi and the series ends with Rin planning to have a child with Daikichi.
- Daikichi Kawachi (河地 大吉 Kawachi Daikichi )
- Daikichi is a 30-year-old single man and the adoptive guardian of Rin. With Rin living in his home, Daikichi quits smoking, cleans his house, and reluctantly cuts back on work hours. Despite his irresponsible life style, Daikichi is a very hard worker and considered the best in his department. He is insecure about his style on raising Rin, always asking his co-workers or Yukari for guidance. Yumi Unita stated some events Daikichi faced when raising Rin were based on her personal experiences. He appears to like Yukari. He is voiced by Hiroshi Tsuchida in the anime and portrayed by Kenichi Matsuyama in the live action film.

Rin begins to wrestle with her feelings when Kouki starts wanting to have a deeper relationship with her. Rin comes to realize that she likes Daikichi, but is hesitant to pursue a relationship because they are related. Near the end of the series, however, Rin learns that Souichi was not her biological father and only adopted her. After this she opts to stay with Daikichi for life and marry him. Her child self is voiced by Ayu Matsuura in the anime and portrayed by Mana Ashida in the live-action film.

His child self is voiced by Noa Sakai in the anime and portrayed by Ruiki Satō in the live-action film.
- Yukari Nitani (二谷 ゆかり Nitani Yukari )
