In a world where werewolves live among humans in secret, Han Ji-u, a detective agency owner and a powerful werewolf, crosses paths with Cheon Yuseung, a famous actor, when he "accidentally" hits her with his car.

And when they run into each other again "by chance," one thing becomes clear to Ji-u: She must have him — whatever that may entail.

Ji-u wants Yuseung’s rare ability to make werewolves stronger through touch. Yuseung, on the other hand, wants information on key figures in the werewolf world to eliminate them.

Will they each get what they’re after? Or more importantly — will they fall in love?
