　　University student Wan has a fanboy hobby, following and photographing rising star Nine. When Wan gets a casting opportunity for a support role in a Y series his idol will be starring in, he meets Third, a sharp-tongued leading man and Nine's ship partner. The two clash immediately, but when Wan passes his audition, the two are forced to work together. Despite their dislike for one another, after getting to know Third, Wan starts to look at his rival in a different light. He doesn't know what's wrong with him, but he finds himself avoiding the cocky leading man's gaze more and more often.

　　Beyond that, Wan comes to learn that behind the curtain, the industry that looked so splendid isn't all as he'd thought. Even Nine, his own idol, is hiding something shady.
