Sing it!

Mun Do-Hyeon, the manager of the popular idol group Byrex, rushes to a gay club after receiving instructions to "bring the member back before he causes trouble." There, intoxicated, Do-Hyeon impulsively has a one-night stand with Seo Jun-Hyeok, a man who feels unfamiliar yet somehow familiar. The next day, Do-Hyeon realizes that the man from the previous night is Seo Jun-Hyeok, a popular composer who is now a success in the industry and a junior from his high school club who had confessed his feelings to him in the past only to be rejected. What makes the situation even more awkward is that they are bound to run into each other frequently at work. Coincidentally, the group Do-Hyeon manages receives a song from Jun-Hyeok, and the two become entangled professionally. Concerned by Jun-Hyeok's changed attitude and gaze, Do-Hyeon begins to look into his personal circumstances and past emotions he was previously unaware of. For Do-Hyeon, who once dreamed of becoming a musician but was frustrated and has been living in compromise with reality, this reunion with Jun-Hyeok is not just a simple happening. It serves as an opportunity to confront forgotten and abandoned dreams and closed hearts again, and the relationship between the two begins to flow in a new direction.
