Going home for his grandfather’s funeral, thirty-year-old bachelor Daikichi is floored to discover that the old man had an illegitimate child with a younger lover! The rest of his family is equally shocked and embarrassed by this surprise development, and not one of them wants anything to do with the silent little girl, Rin. In a fit of angry spontaneity, Daikichi decides to take her in himself! But will living with this overgrown teenager of man help Rin come out of her shell? And hang on, won’t this turn of events spell doom for Daikichi’s love life?!
When 30-year-old Daikichi returns home for his grandfather’s funeral he meets an unfamiliar child in the garden. His mother explains that Rin is his grandfather’s illegitimate daughter by an unknown mother. The girl is an embarrassment to all his relatives and nobody wants to take her in because of the scandal. 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’s grandfather dies, leaving behind a young daughter named Rin. However, as most of the family is embarrassed at the idea of a 79-year-old man having a six-year-old child, they can’t seem to figure out what to do with her. Disgusted by this behavior, Daikichi decides to take care of her himself, but he’s a bachelor, has no idea how to raise a child, and doesn’t even like kids! Now, Daikichi must do the normal things a parent does such as enroll her in school, buy her clothing and teach her about the life and world around her. But more importantly, he must also help her deal with her father’s death and decide whether or not she should try to find her mother. Together, the two begin their unlikely relationship as father and daughter.
