In the glittering world of K-pop, fame comes at a steep price - time with family, personal freedom, and above all, the chance at love. For Yena, a rising star and beloved member of the girl group Hera, these sacrifices have long been part of the deal. When she's given the rare opportunity to collaborate with Woozi - member of global sensation Seventeen and the genius producer behind many songs - their duet is poised to dominate the musical charts. But as studio sessions turn into stolen moments, and professional chemistry gives way to something deeper, their connection threatens to cross a forbidden line. In an industry where romance invites scandal and secrecy is survival, Yena and Woozi must choose between their growing feelings and the careers they've worked their entire lives to build.
