“Ahn Se-jeong’s body, from head to toe, belongs to Do Ji-hoon.” “Now that the owner’s back, the mutts should get lost.” Ahn Se-jeong works passionately at a major advertising agency. As she fights her way toward success, a man from her college days—her bad fate, her first love, and the biggest mistake of her life—Do Ji-hoon, reappears before her. And this time, he has no intention of letting her run away. “…Love me again. As soon as possible, if you can.” Se-jeong knows this relationship might become another mistake. Between cold reason and burning desire, their dirty, obsessive romance begins once more.
