30-year-old bachelor businessman Daikichi Kawachi encounters Rin, a girl he's never seen before, at his grandfather's funeral. Surprisingly, the 6-year-old girl turns out to be his grandfather's love child. Daikichi doesn't like children, but the cold attitude of his relatives towards Rin makes him uncomfortable. And then, the relatives' meeting to decide who will have custody of Rin begins at last...
