I was a nobody—a struggling rock vocalist with a raspy voice and a career going nowhere. My twin brother, Eunwoo, on the other hand, was an idol in a rising K-pop boy group. He was supposed to join their comeback… until a broken leg put him out of commission.

His solution? Me.

Now I’m stuck living in a messy dorm with four men, training like a machine, and pretending to be my brother in front of screaming fans. It’s only for three months, they said. Just keep the act together, they said.

But here’s the real problem:

Somewhere between rehearsals, late-night ramen, and the suffocating smell of sweaty socks, I’ve started noticing the way the members look at me. And I can’t tell if they’re falling for me… or for the Eunwoo they think I am.

Three months in this madhouse.
Four suspicious idols.
One giant secret.

And if they find out the truth, will this act end with my heart on stage—or in pieces?
