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.
Daikichi is a 30 year-old single man working in a clothing company. He is diligent and capable but sometimes a bit lazy. He is not good at dealing with women or children.
Rin is a 6 year-old girl but she seems to be very mature in some aspects. She is the illegitimate daughter of Souichi, Daikichi's grandfather, which makes her an aunt to Daikichi.
