Kang Rakwon, a former idol turned entertainment agency CEO, is shaken by the news that his ex-teammate, Lee Do-un, has taken his own life.
Ten years earlier, their idol group Delight disbanded after what Rakwon believed was Do-un's betrayal. Carrying years of resentment and regret, he attends the funeral—only to fall asleep beside the memorial altar.
When he opens his eyes, he's somehow traveled twenty years into the past.
But this isn't the future he remembers.
His teammates are already drifting apart, each burdened by insecurities and hidden wounds that threaten to destroy the group before it ever has a chance to shine.
"Everything always comes so easily to you, hyung."
"Do it without me. I don't want to sing anymore."
"I'm... I'm not talented enough. There's no way anyone would want to perform a song I wrote."
Determined to rewrite fate, Rakwon vows to prevent Delight's breakup and save Do-un from his tragic end.
Can one man change the future, and bring his broken team back to the top?
