After the man who raised her like a daughter is murdered, a girl uses her save-and-load ability to turn back time to the only point when he was still alive: when she was seven years old. Determined to change their fate, she starts life over in hopes of creating a happier future. But things take an unexpected turn when a close friend confesses to her, and she discovers that he can remember every time she resets time—along with all the embarrassing things she thought no one would ever know.
