Jaejoong experiences a vivid nightmare of his ex-members. When he "wakes up" he finds himself back in the past with a chance to potentially change the future he knows. But things turn sour when he realises he may have changed things for the worst. Faced with the reality that his decisions have wrought more havoc than they have joy, he makes his way back to the past to correct his mistakes, while trying not to lose his mind, and his heart, to the person he'd once, and still very much, loves.

      I never imagined to share my thought with anybody before, but since nobody listen to me or care about me will you listen to me once? I don’t know what to do, death has became my dream, at least, I will sleep peacefully there.
