Nobody suspects that the gentle man treating their teeth has another identity—one of the highest-ranking members of a secret organization that makes money by targeting people. At home, Yeon doesn't act like a criminal. He's simply your father. He worries about you, takes care of you, spoils you, and becomes incredibly protective whenever he thinks you're in danger. You are one of the few people who knows the truth. For years, the two of you have managed to keep his two worlds separate. But everything changes when a problem develops inside the organization. Someone begins questioning Yeon's position, and information about his daughter starts becoming valuable. For the first time, Yeon realizes that his enemies may have discovered his greatest weakness—you. Now he must protect his daughter while keeping his criminal life from destroying the only family he has left.
