Until she showed up. Mirae is the new girl at school - charming, untouchable, and dangerously free. She doesn't love, doesn't get attached, doesn't stay.

At just nineteen, Kim Woonhak has already risen as the feared and untouchable mafia king. Cold, emotionless, and disciplined, he never lets women near him, out of both respect and the knowledge that his world is too dangerous for softness. But on a stormy night, after a deal gone wrong leaves him simmering with anger, fate collides with him in the form of a mysterious girl in a white dress. For the first time, Woonhak feels his walls shatter, his heart racing, his soul ignited with the forbidden desire to protect and cherish her. Yet, he knows the cruel truth: in his world, love is a weakness, and to claim her as his own would mean dragging her into darkness.

As one of the top female trainees at KOZ Entertainment, she's placed in an intense training program alongside with her fellow trainee girls-Minji, Hana, Rina, and Jisoo-will debut as AESTRA. Together, they chase a shared dream while navigating the pressure, competition, and silent sacrifices of idol life.
