Mason Carter has the perfect roommate. Adrian Bennett cooks his meals, reminds him to eat something other than instant noodles, and somehow puts up with his terrible sleeping habits. They bicker over groceries, steal each other's clothes, and spend most evenings together on the couch. They're practically an old married couple. At least, that's what Mason likes to joke. Then Adrian drops a bombshell: he's gay, his ex-boyfriend is getting married, and he needs Mason to pretend to be his boyfriend at the wedding. Easy enough, right? Except one fake kiss turns out to be a little too convincing. Suddenly, Mason can't stop noticing Adrian's lips, his hands, or the way his heart races whenever they get too close. And when Adrian finally gets tired of waiting for something that may never happen, he starts pulling away. No more late-night meals together. No more falling asleep on the same couch. And worst of all? Adrian starts dating someone else. Mason insists he's not jealous. He's straight, after all. So why does watching another man make Adrian smile feel like losing the one person who has always been his home?
