Main character is a thief who is often put to custody by the police. On one of such returns from the custody he saves a girl from a running car, and falls unconscious afterwards. When he wakes up, he sees a grim reaper who explains that protagonist experienced a temporary death, and now he is given ten days to show whether he deserves to live on or should die. The boy, the girl and their supervisors - the devil girl and the angel girl - start to live under the same roof for ten days.
