"The kind of play I prefer is a little too hardcore for newbies."

Seo-ha, a university lecturer, is a natural submissive with deeply ingrained masochistic tendencies. Yet, fear of being outed has kept him from ever pursuing a real partner, leaving him to indulge only in fantasies.

When the fellow professor he has been secretly admiring announces their engagement, Seo-ha is devastated. In a moment of impulsive rebellion, he turns to a BDSM community to find a one-night play partner, hoping to finally experience the domination he's always craved.

But this leap into the unknown may lead him down a path far more intense—and dangerous—than he ever imagined.
