Baebin, as the eldest and leading member of the beloved K-Pop group, Insatiable7, is assumed to have everything figured out. However, he grapples with responsibility and uncertainty about what lies ahead for himself and IN7.
 
He is taken aback by a beautiful woman who tilts his world. Intrigued, he discovers Go-Ri is more than simply attractive—she is also a musical prodigy. Baebin is deeply impressed by her emotionally driven, soulful artistry. But before they can connect, she must first accept that he could be something more than anyone else she’s ever met.
 
Haunted by a life-altering incident from her past, Go-Ri hides in the safety of teaching music, shying away from fame. But this polite, handsome man starts challenging her defenses. Baebin works to balance his desires for her, and his career with his best friends. She finds herself torn between maintaining her protective barriers and letting him in.
 
But how close can Go-Ri let this stranger get when he is a reminder of her most dangerous mistake? Can Baebin protect and serve the group while also writing a new song for himself?
