Areum Ham can't believe that one night of drinking to forget meant forgetting everything. But when Bumyeong Baek, soccer star and childhood friend, demands to know what they did the night before, one thing slowly becomes clear: neither of them remembers if things ended with a kiss. But just when she thinks things are complicated enough, he has another demand lined up for her. Since when was he interested in more? Does she feel the same way, or has this tiger set his sights on the wrong prey?
