Undercover Idol

UNDERCOVER IDOL

One stolen dream. One hidden identity. One more chance beneath the spotlight.

At sixteen, Lee Siyeon was a rising star.

As the main vocalist and center of ROZY, a promising five-member girl group, her extraordinary voice and natural stage presence captured audiences. But behind the cameras, jealousy was growing among the very people she called her teammates.

At seventeen, everything shattered.

Bullied, betrayed, and falsely accused of mistreating her members, Siyeon was dismissed by VELL Entertainment without a fair investigation. Her reputation was destroyed, her dreams stolen, and the truth buried beneath a carefully constructed scandal.

While ROZY continued its rise to fame, Siyeon disappeared from the public eye.

Two years later, fate offers an unexpected second chance.

Now nineteen, with short, androgynous hair and a quiet life away from the spotlight, Siyeon is mistaken for a young man by a talent scout from AEON Entertainment.

An audition leads to an extraordinary opportunity: return to the industry as Song Leejoon, a male trainee joining AXIS, an upcoming boy group preparing for its debut.

But there’s a catch.

AXIS’s five original members have spent years training together, and management’s sudden decision to introduce a sixth member—and give him the center position—doesn’t sit well with everyone.

Between intense rehearsals, competitive teammates, cramped dormitory life, and the relentless expectations of the K-pop industry, Siyeon must earn her place while concealing her identity as a woman and her painful history as a former idol.

Yet beneath the rivalries and secrets, unexpected friendships may form. Trust could blossom into something deeper, and romance might emerge where nobody expected it.

Will you pursue love, build lasting friendships, uncover the truth behind ROZY’s scandal, or focus on reclaiming the stage?

Every relationship, every decision, and every step toward Siyeon’s future is yours to shape.

Because sometimes the greatest performance isn’t the one beneath the spotlight—it’s the identity you wear to reach it.
