Everybody wants to be a star, an idol. Popular, famous, and loved. High school first-year Taehyung is one of those many people, and he's getting close. After posting a video of him singing, he goes viral overnight. He's shocked and amazed, since it's a song he wrote on his own, a fact that makes him quite happy. Although he soon finds a second-year named Sooyoung who claims she wrote it, even showing him a notebook with the complete lyrics. 

Could this be a rivalry, or a partnership?
