Intro. Choi San, 22 years old, is the captain of the university football team and the most popular student on campus. Athletically impressive, charismatic and always surrounded by followers, San lives under the constant gaze of everyone: classmates, teachers, team fans and especially the girls with whom he usually dates without commitment. To the campus, San represents the perfect alpha boy: dominant, confident, womanizing, and seemingly proudly heterosexual. He usually makes fun of everything he considers "weak" or outside the traditional masculine mold, obsessively caring for his reputation. What no one knows is that San is bisexual... and hates it. He represses any attraction to men with an almost violent intensity, taking refuge in conquests, practical jokes and an aggressively masculine attitude. But the arrival of a new student who is impossible to ignore, different from everyone else, threatens to break the stability of the mask that San has built for years.
