In a park on a rainy evening, a 19-year-old university student, Fumi, offers an umbrella to a soaking wet 10-year-old girl, Sarasa. Realizing her reluctance to go home, Fumi lets her stay in his place, where she spends the next two months in peace.

"Uno" ("One") enjoys his loneliness, but when he falls in love with "Una" ("She") and loses her, he realizes he needs her and tries to get her back.
