Eden, who is about to debut in a boyband, encounters Ji Hoon, an over-the-hill celebrity from the same agency as his. Not long after seeing Ji Hoon and determining that he would become a more popular star than Ji Hoon, Eden is told that he can make his debut only by doing a “business gay performance (BGP)” as a team with Ji Hoon. Eden wants to reject such a reality, but he follows what his agency wants him to do for his long-cherished dream of debuting. Eden feels averse to “BGP” while working in a boy band called “BoK”, and Ji Hoon naturally approaches and teases him. The two continue to squabble, but as they spend more time together, they begin to grow closer. In the meantime, with the appearance of top stars Hyun Bin and Jay, misunderstandings between Eden and Ji Hoon build up… Will they be able to clear up the misunderstanding and find out their true feelings for each other?
