Rumi thought the worst part of being a trainee was surviving monthly evaluations.
She was wrong.
After witnessing a shadow creature crawl out of a mirror in the practice room, her world turns upside down. The only person who believes her is Jinu—quiet, unreadable, and far too calm for someone who just fought off a demon with his bare hands.
"Stay close to me," Jinu warns. "The moment you awakened that mark… they started hunting you."
Now every stage hides a threat, every fan chant echoes with warnings, and every performance could become her last.
But Rumi refuses to run. If her destiny demands she fight…
Then she'll face the darkness head-on—
even if it means becoming the idol the demons fear the most.
