Returning home from his part-time job, Arata is persuaded by Ryou Yoake, an employee of ReLife Research Institute, into participating in an experiment which will help him overcome his difficulties and re-enter corporate life. As part of the ReLife experiment, Arata's physique is reverted to that of a 17-year-old, and all he must do is relive his high school life for one year.
