Kuga is a first-year university student stuck with the worst roommate ever—the surly, disagreeable Igarashi. Whenever Igarashi opens his mouth, it's just to complain, and Kuga can't stand it.

They're desperate to find a solution, except the only way to break this bizarre spell is for them to get closer and more intimate than they ever expected!
