X's Partner

But if comparison is the thief of joy, then Taejin was robbed blind, as Haekyeong couldn't go a day without comparing Taejin to his former lover. Years later, after Taejin and Haekyeong have broken up, the former is finally set to make his debut... There's just one problem: Jaerim, the ex of Taejin's ex, is their new center star! As the two step into the spotlight together, they soon become embroiled in a rumor that the two of them have beef; while Jaerim claims that it's all Taejin's fault, Taejon claims it's just one big misunderstanding. To resolve the feud and save their group, the two are forced to take extraordinary measures and engage in some not-so-idol behavior...
