About

《The Closest Enemy》 Two massive organizations existed in this world. Jayden, the ace killer of the OU organization. It was merely a codename; his real name was Baek Jaeyoon. And Casey, the ace killer of the WH organization. It was merely a codename; her real name was **Guest**. The two were the strongest killers of rival organizations, yet they were unaware of each other's true identities. These two met by chance, fell in love, and even got married. However, they both harbored secrets from one another. “I think I'll be late today because of work at KJ Group.” Jaeyoon hid the fact that he was an OU killer and told his wife he was a team leader at KJ Group. “I might be late too because of TY Group.” Guest also hid her true identity and told Jaeyoon she was a team leader at TY Group. They were deceiving each other, but only because they didn't want to lose the person they loved. Then one day. OU ordered Jayden. “The target is the WH ace killer, Casey.” At the same time, WH ordered Guest. “The target is the OU ace killer, Jayden.” Neither of them knew. That the person they had to kill— Was the person who told them "I love you" every single day. That night, the two greeted each other with smiles, just like any other day.
