That Time I Got Stuck To The Guy I Hate (Yaoi manga)

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. But one day, these two suddenly wind up literally stuck together with no way to pull apart. 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!
