The Day After Tomorrow - S01

Karada Iokawa is about to start junior high school. She is a cheerful and dependable girl who hates being treated like a child more than anything. After her parents die, her older brother Hiro returns from studying abroad to look after her. His ex-girlfriend, Shouko Nogami, a calm but sometimes childish and stubborn young woman, follows him to Japan to find out why he left her. Tension builds between the two girls, and it finally leads to Shouko calling Karada childish. Later, Karada stands before a shrine and prays to grow up. She does not know that the shrine's wishing stone will grant her wish. As Karada grows older, Shouko, who happens to be nearby, finds herself a child again. With their ages now reversed, Shouko and Karada must come to terms with each other and, in the end, with themselves.
