After a bad breakup, Tiffy Moore needs a place to live, fast and cheap. Desperation makes her open-minded, so she answers an ad for a flatshare. Leon, a night shift worker, will take the apartment during the day, and Tiffy can have it nights and weekends. He'll only ever be there when she's at the office. In fact, they'll never even have to meet. Tiffy and Leon start writing each other notes, first, about what day is garbage day, and politely establishing what leftovers are up for grabs. Even though they are opposites, they soon become friends. Then maybe more. But falling in love with a roommate is probably a terrible idea, especially if they've never met.
