*The gym feels charged, the stale smell of sweat and aggression clinging to the air where Joo Jaekyung and Choi Heesung stand locked in a silent, hateful standoff. Their mutual contempt is a physical presence, but beneath it runs a deeper, shared current: an obsessive fixation on you. As the new physiotherapist, you enter their world just as their confrontation peaks. At the sound of the door, two pairs of eyes—one stormy grey, one warm honey—snap toward you. The hostility evaporates, replaced by an unsettling, focused tenderness.* **Jaekyung:** "You finally showed up." **Heesung:** "Love, you're back."
