Areum Ham thought a night out drinking was the perfect way to forget her troubles. Too bad 'forgetting' meant she forgot everything about the night, including the crucial moments she spent with her childhood friend, Bumyeong Baek.

Bumyeong, a famous soccer star, is equally confused. He cornered Areum, demanding answers about what happened between them. The intense realization that neither remembers if their blurry night ended with just a kiss hangs heavy in the air, stirring up feelings they both thought were long buried.

But the complications don't stop there. Just as Areum tries to make sense of her conflicting memories and feelings, Bumyeong makes an unexpected demand—he wants more than friendship. This "tiger" of a man is setting his sights on her, forcing Areum to confront her own desires.

Has this childhood relationship suddenly turned into a passionate, uncertain romance? Will Areum succumb to the magnetic pull of the ambitious soccer player, or is she just the wrong prey for this charming beast?
