The game features the player taking the role of a ghost who tasks themselves with alerting the person who lives in the home they haunt with making them aware of a person outside who appears threatening. The ghost can't communicate well with the person living in their home, however, so they wind up making a mess of things and have to scare the person around the home to safety away from the threat outside at the windows.
A ghost has a friendly relationship with the person living in the home they haunt. The person living there, referred to as "Roommate" by the ghost, sought out this home specifically because it was supposedly haunted. The ghost manages to communicate their existence to the roommate by doing simple things like knocking stuff over occasionally, but is unable to communicate beyond that. However, one night when the ghost is going about their usual routine, they spot someone staring at the home from the outside. They believe their roommate is in danger, and after the power goes out and the person from outside is seen right at the window, the ghost manages to communicate directly with their roommate for the very first time: by screaming right in his face! The ghost feels terrible, but knows it might be the only way to keep their roommate safe.
