Nine years after their last encounter, Koo Seung Hyeok and Kwon I Hyeon unexpectedly reunite at Nexus, a nightclub linked to organized crime. Seung Hyeok, now the club manager, confronts I Hyeon, who works in lowly conditions, leading to a series of hostile interactions rooted in past grievances. When I Hyeon’s father is diagnosed with cancer, he reluctantly re-engages with Seung Hyeok under a work and debt agreement. This forced collaboration ignites complex emotions, as hatred and fixation intertwine. As both men grapple with their tumultuous history—Seung Hyeok's contempt and I Hyeon's struggle with vulnerability—they face the choice between continued conflict or an unforeseen future together. ~~ Adapted from the web novel "Winter Season" (동절기) by Iromil (이로밀).
