Plot
Haruto Sumimura is a senior high school student. On Haruto's birthday, his girlfriend Mei Nakajima prepares a surprise party for him at his house. To keep Haruto away from the house while they prepare, Mei asks him to go to their school and retrieve her wallet. There, he walks into a shocking scene. While trying to get help, he is hit by a car and dies. 12 years later, Haruto wakes up at the roof of his school building, and he meets Mei again. Although Mei and Haruto were born in the same year, the two childhood friends end up being 12 years apart because they have aged at different places (worlds) for some strange reason. Now Mei is a 31-year-old woman, but Haruto is still a 19-year-old boy. With the assistance of his friends and Mei, Haruto sets out to make things right for his family and solve the mysteries surrounding his death and resurrection.
