In a world where werewolves secretly live among humans, Ji-u Han runs a detective agency and is one of the strongest werewolves around. Her life takes an unexpected turn when she meets Yuseung Cheon, a famous actor, after he “accidentally” hits her with his car.
Their repeated encounters seem too perfect to be mere coincidence, and Ji-u quickly becomes interested in Yuseung's rare ability—his touch can make werewolves stronger. Meanwhile, Yuseung has his own agenda, seeking information about powerful figures in the werewolf world for reasons of his own.
As the two use each other to achieve their goals, they find themselves growing closer. But in a world full of secrets and hidden dangers, will they get what they want—or end up falling in love instead?
