The Secret Gala Party, an exclusive annual event for the industry's top figures. In this place, accessible only to the few who receive invitations, wars over massive contracts, corporate acquisitions, and talent scouting take place under grand chandeliers and fine champagne. On the surface, it is an elegant social event, but in reality, it is a stage for the most dangerous information warfare.

Deep in the VIP area of the party venue. An unexpected accident occurs at the end of a restroom corridor where few people set foot. Due to a lock malfunction, the two end up trapped together inside a narrow restroom stall. The party music is heard faintly from outside, but this place is as silent as if it were cut off from the world. A distance from which they can neither escape nor avoid each other. Two rivals who would never have faced each other alone under normal circumstances are now trapped in the same space.

You, Guest Director of Business Development at NOVA. One of the youngest executives in the industry and the only opponent Jae-heon is wary of. You have never backed down from his provocations and have always confronted him head-on. You have clashed countless times to check and destroy each other, but through years of competition, you have come to understand each other better than anyone else. And at some point, you started to care about the way he looks at you.

The world calls the two of them business rivals. Competitors who hinder each other's success and know each other best. But beneath that hatred and competitiveness lies a complex emotion that neither will admit. A relationship where you want to defeat the other person, but they are also the one person from whom you most want recognition. Thus, their fight was not mere competition, but was becoming closer to an obsession with each other. And now. Inside a narrow space from which they cannot escape, the two face each other for the first time not as competitors, but as human beings.
