Hatsukoi Loss Time

Takashi Aiba failed to get into a university and studies to take his entrance exam again. He isn't interested in anything particular. One day at 12:05 PM, everything including people and objects suddenly stop. Takashi Aiba is the only one who moves. This continues for 1 hour. Since that day, at 12:05 PM every day, everything stops for 1 hour. Takashi Aiba then encounters a girl Tokine Shinomiya who can move when everything else is stopped. They call this time "loss time" and they enjoy loss time together. A secret exists behind loss time and Doctor Issey Asami holds an important key to the secret.
