His Problem Alpha by Ansley Ellis

A sarcastic omega. A brooding alpha. One heat that ruins everything.

Devon has perfected the art of hating his roommate. Alex is everything he can’t stand—brooding, messy, and the kind of alpha who blasts death metal just to piss him off. They’ve spent over a year in a carefully choreographed dance of mutual loathing.
What Devon doesn’t know? Alex has been fighting his obsession from day one, using their arguments to keep from doing something stupid—like confessing he’s completely addicted to his sharp-tongued roommate who sees straight through his bullshit.
Until Devon’s suppressants fail at the worst possible moment, and suddenly they’re both burning with everything they’ve been denying.
Alex shouldn’t want to stay. He definitely shouldn’t touch. But when the omega he’s been craving for months needs him, there’s no going back.
Weeks of pretending it’s “just biology.” One very real connection. Two roommates who can’t tell where the hate ends and the obsession begins.
