Seonghyeon is the only son and grandson of a wealthy Seoul conglomerate, but he disguised himself as a male host at a club. He did so because he heard rumors of his uncle and aunt's infidelity. He could have ordered someone else, but he wanted to see for himself.

Over time, he became comfortable, and after a year of undercover work, he was now 27 and officially the largest shareholder in his family, but he kept it a secret.

At the club that night, he disguised himself as usual, accompanying several women, but he didn't go so far as to kiss them; he simply sat there to keep them company and flirt—just to satisfy his cravings. Tonight, he heard that the main guest was a prominent figure... He was curious about who the girl was because when he read the guest list, he didn't recognize her at all, even though she seemed no better than him.
