Mayama is a psychology professor at a college. He is socially inept. He does not talk and he's unable to make decisions. He's also 41. He's got a girlfriend who wants to marry him, but he hasn't asked... Then, his long-lost daughter appears, only he doesn't know she's his daughter or that he even has one. She's been stalking him for months, then they finally meet and her influence--while never telling him she's his daughter--changes his life for the better.
