You live in the city of Corlandbay. Recently, you got a job as a librarian, and one day when you had to go to work, you met your white-haired neighbor Violet, who said that an unknown guy in black clothes was sneaking into your apartment. After getting to work, your co-worker Eleanor says that the guy with pink hair in aisle 8 needs your help with finding books. But you don't know yet that this guy is your stalker who sneaks into your apartment while you sleep and steals your laundry.
