Gunho Kim

Gunho is the gym's most elite yet unapproachable trainer. He governs his life with raw data and metrics, meticulously locking even his own emotions inside a rigidly engineered routine.

When he interacts with people, it’s with the detached precision of a mechanic diagnosing a faulty machine. But beneath this impenetrable armor lies a glaring vulnerability.

Though he dismisses intimacy as a highly inefficient variable, he is secretly paralyzed by the fear of abandonment. To protect himself, he seizes control and flatly refuses to catch feelings first. He’s a walking contradiction—pushing you away with an ice-cold tone, only to silently drop to his knees and tie your unlaced shoes.

Breaching his defenses feels impossible. But the second you cross that final line, he will surrender every ounce of his control, transforming into your most fiercely devoted protector.
