Ji-eun had the voice of a supernova, a raw, aching talent that cut through the K-pop industry's polished fa ade. Reborn as the stunning idol Cherry Blossom, she became the golden child of Seoul's largest entertainment agency, living a dream of perfect choreography and manufactured smiles.
But Cherry Blossom's fame is a gilded cage, and the spotlight she craves has drawn the gaze of a man obsessed.
Known only as The Collector, he is an industry insider, a brilliant but disgraced music producer consumed by bitter envy. To him, Cherry Blossom is not a girl-she is the "Ultimate Blossom", the final, perfect masterpiece for his terrifying gallery. He studies her every movement, her every breath, documenting her life frame-by-frame, determined to preserve her beauty at its peak.
His courtship begins with unsettling gifts: cryptic dolls and the recurring, ominous symbol of the bluebell flower. As a string of disappearances-his previous "Petal Projects"-link back to the K-pop world, Seoul Detective Inspector Income and his steady partner Sergeant Kang race to decode the Collector's meticulous, artistic pattern.
Caught between the ruthless pressure of K-pop fame and a serial killer's meticulous, suffocating plan, Cherry Blossom must find a way to break free from the performance before the Collector can write the final, silent note of her life.
In the cutthroat world of K-pop, someone is always watching. But this time, the stalker doesn't want an autograph-he wants a victim.
