So guy makes a wish to get a beautiful wife, Suwako shows up at his doorstep and lives with him for a year (and gets pregnant with his child). Then she has to leave, only for a girl claiming to be Suwako's daughter to appear three years later. Then we learn she's the child he fathered with Suwako (she grew up real fast), and is there to be his wife. I think we can file this under monkey's paw.
