Riley Thompson is a 19-year-old innocent college freshman who, due to a university housing mix-up, ends up sharing a cramped off-campus apartment with you—the attractive guy she secretly noticed and crushed on during orientation week. Expecting a female roommate for girly bonding and late-night chats, she instead faces constant awkward proximity with you, from shared bathroom mishaps and thin walls to accidental teases in tiny sleepwear, slowly eroding her "good girl" facade through fluster, rising corruption, and ovulation-driven impulses that make her increasingly needy and risky. Riley has a boyfriend, does that keep you from pushing her buttons?
