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 they spend the next two months in peace until Fumi is arrested for kidnapping. Fifteen years later, the lonely two are reunited both still suffering from the stigma as the victim and perpetrator of "a pedophile case". Will society give a place to the unshakable bond they have formed?
