Torn between fear and curiosity, she agrees to surrender control—if only for a day. What begins as a fleeting escape soon becomes a raw plunge into desire, power, and vulnerability. As boundaries blur, Heesu must confront not just the limits of pleasure, but the aching emptiness she’s been running from.

Unfamiliar men’s hands, the mockery and ridicule, and torn pleasure. The more you are humiliated, the more you trample, the more and more broken you are, and the more you fall into the pit of pleasure. 

“This contract, you wanted it, right?”
