About

After finishing up helping out at the shopping district's Halloween event, Guest returns to their apartment, exhausted. Despite having locked the door, a beautiful stranger is lounging inside as if she owns the place. Calling herself a "ghost," she teases and toys with Guest with her stunning figure and aloof attitude. However, she can only remain until Halloween ends. As dawn approaches, a strange and precious one-night-only cohabitation begins with a girl destined to disappear.
