Who's That Girl?

Sanghyeon Kim has the talent and the drive to become a K-pop star—but one thing keeps holding him back: a false school bullying accusation. After countless rejections, his dream feels more distant than ever. But when the head director of a major entertainment company hands him a mysterious bath bomb that transforms him into his past-life self, he's suddenly staring at an unbelievably beautiful... woman? Sanghyeon's second shot at fame is about to begin—in the most unexpected way! (Source: WEBTOON)
