Two secrets. One bet. Who will break first? Selena Gomez can't decide if she wants to kiss her new college roommate or punch him. On the one hand, Justin Bieber is a handsome honey brown-eyed bundle of charm. On the other, he's a tattooed, guitar-playing bad boy. Maybe that's why Selena's afraid of falling in love with him, or anyone else. She doesn't want to get burned, so she needs him gone before it's too late. Justin himself has been burned before, but Selena's sexy laugh and refusal to let him get away with anything make her irresistible. Determined not to be kicked out of her life without a fight, Justin proposes a bet: if she can convince him she either truly loves or hates him, he'll leave the apartment;and leave her alone. But when the man behind Selena's fear of giving up her heart resurfaces, she has to decide: trust Justin with her greatest secret, or do everything in her power to win that bet and drive him away forever.
