Summary
Cha Ian and Baek Seowoo have been rivals for over 20 years, harboring deep resentment. One day, Cha Ian and his half-brother Cha Yihyun become trapped in a room with Seowoo. Unable to escape, the three are forced into intimacy—literally—leading to unexpected shifts in their dynamics. The story is structured around an “Alpha Dominant × Alpha Recessive × Alpha Dominant” triad, set in a confined space where they can only leave by engaging sexually.
Through their forced interaction, the long-standing antagonism starts to blur into something more complex—affection, desire, and emotional entanglement begin to surface among the trio.
