Off-Key and On Edge

Two elite perfectionists. One sheet of ice. And a symphony born of pure friction.

Jake Sim lives his life by the numbers. Top of his biology class, star vocalist of the music department, and a guy with a bright smile hiding a history of sharp trauma he desperately tries to outrun.

His only problem? Park Sunghoon.

The campus prince, a national-level figure skater, and the arrogant genius. Jake loathes him. He hates Sunghoon's icy perfection, his suffocatingly broad build, and how tiny he feels whenever Sunghoon looms near.

Sunghoon doesn't do warmth. Raised by cold parents, he built a fortress out of flawless triple axels, grueling gym hours, and an impenetrable silence. He has no time for rivals-especially not a stubborn, soft-eyed vocalist who flinches at his shadow.

But when the university forces them to co-headline the high-stakes Glacier Gala, their bitter rivalry is shoved into the spotlight. Jake has to sing live from the center of the rink while Sunghoon translates his voice into movement on the ice.

The ice rink is about to get explosive. Forced together, they'll have to face the thin line between intense hatred and a burning, undeniable chemistry-and learn that sometimes, the most beautiful harmony comes from being entirely off-key and on edge.
