Echochain

Echochain (Yoo Min-Seok) Origins

Yoo Min-Seok once reigned at the top of the K-pop charts, adored by fans and celebrated across the industry. Her world began to crumble when a rising young star, Yoon Ha-Eun, burst onto the scene and stole the spotlight. In the months that followed, Ha-Eun’s popularity soared while Min-Seok’s career faltered, eventually pushing her out of the charts entirely.

Swallowing her pride, Min-Seok reinvented herself as a composer and trainer, guiding the next generation of idols. But beneath her professional smile simmered a deep resentment—a festering bitterness that slowly gave rise to something darker. Her unyielding hatred manifested into a powerful force, awakening abilities she never knew she possessed.

Her fury sharpened into obsession when she uncovered Ha-Eun’s secret: the rising star was actually Muse, a celebrated superhero. Seizing the opportunity for revenge, Min-Seok abandoned her old life, crafting a new identity as Echochain. Now, she works from the shadows to ruin Muse’s career, reputation, and life—one calculated strike at a time.
