There are tenants who are behind on rent due to alcoholism, a virgin who has failed the college entrance exam ten times, a resident confined to home due to an accident, and a voyeur who watches the masturbation of the tenant in room 102... This is a story of solving various problems with tenants using a K-cup voluptuous body.
