あらすじ
Assistant Manager Yi-Wol Kim has spent five years working a day job—and five years doing “stand-in stanning” for his boss’s daughter’s favorite idol group, Spark. During yet another Spark-related overtime, he collapses… and wakes up nine years in the past with a second chance at life. But this chance comes with a cruel condition: to undo his sister’s death, Yi-Wol must debut as a member of Spark himself. Thrown into the idol life he never wanted, he’ll have to survive fame, internal politics, and his own reluctant heart.
