Introduction: Fang Cheng and Jiang Yu have been frenemies since childhood. When their families pressure them into an arranged marriage, they make a deal: it's all just an act. They'll play along and get it over with. But somewhere along the way, the act starts getting a little too real. They kiss. They hug. They even get used to how the other sleeps. While outsmarting a meddling aunt and dealing with a scheming ex, they also find themselves secretly falling for each other. And then it hits them: Oh, crap. Has Fang Cheng somehow turned her best bro into a real husband?
