“Wait—did you just sleep with me?” Gong So-min was recently dumped by her ex-boyfriend… and left with the humiliating label of being “frigid.” An orgasm? Does that even really exist? One day, still reeling from her breakup, she hears that her first love will be at a party— and without thinking, she rushes there. But the man she runs into instead is someone else— a guy she’d noticed a few days earlier without knowing why she couldn’t look away. His name is Woo Jae-yeol: charisma, looks, power—he’s got it all. ...Though he definitely seems like a player. Then comes one unexpected night. He’s the man who awakens her senses for the first time— and she’s sure she’ll never see him again. “Hey… did you just sleep with me?” The next day, that same man shows up in front of her with his ridiculously handsome face and throws the question right at her. So-min is stunned— “Wait, but… you’re a womanizer, aren’t you?” From that day on, So-min’s peaceful(?) life is completely overturned by strange new emotions and an inconvenient flutter in her heart. It was supposed to be just a one-night mistake… So why does she keep wanting to see him again?
