CNTR (Center) is the top K-pop boy band, and everyone is shocked when one of the members suddenly disappears. Anxious to fill the spot, the role is given to newcomer, Haneul Kyung. Haneul quickly wins the hearts of fans but clashes with the group’s leader, Jiho.

What no one knows? Haneul is actually Hana—a girl—and she’s just joined a boy band under false pretenses. With “Haneul’s” growing fame, Hana will have to choose between her career and her growing feelings for Jiho.
