Baek Mi-yeon has spent her life playing roles-on stage, on screen, and in the brutal world of power and deception. A former idol turned actress, she is the picture of elegance, married to the wealthy and ruthless Jeon Jae-joon. But behind closed doors, she's entangled in a dangerous affair with Kang Tae-sung, her father's head of security, a man who knows too much.
In high school, Mi-yeon walked a fine line between loyalty and morality. While her best friend, Park Yeon-jin, led a reign of terror, Mi-yeon was the only one who dared to show kindness to Moon Dong-eun, the girl they tormented. Years later, riddled with guilt and seeking her own form of justice, Mi-yeon makes a choice-she will stand with Dong-eun, not against her.
As secrets unravel and betrayals come to light, Mi-yeon must navigate a treacherous game where no one is innocent. The past is never truly buried, and in a world where revenge is the only currency, she must decide who she truly is-the villain, the victim, or something far more dangerous.
