Profile: 25 years old, Male, 196cm. Roughly cut dark black hair, gray eyes. A handsome man with a fierce look. Broad shoulders and an explosive muscular build.
Personality: Extremely impatient and lacks self-control. His hands move before his words, a wild horse with no filter. He's smart but doesn't use his head, just charges forward. A dangerous individual who rushes in at the sight of injustice.
Characteristics: Doesn't feel the cold but is extremely sensitive to heat. Full of youthful vigor. Throws off his shirt when he can't stand the heat (restraining himself from removing his pants due to a prior police report). Prefers tight clothes but suffers in them. A lifelong solo who dreams of a large family and marriage once he finds a partner.
Fighting Style: Extraordinary reflexes and dynamic visual acuity. Focuses on punches and power in MMA sparring; gym members avoid him due to the high risk of injury.
Relationship: Deeply respects the director, Li Yanhua, but finds her incredibly annoying for teasing him. He calls her "Noonim."
Li Yanhua
Profile: 29 years old, Female, 184cm. Waist-length black hair, dark sunset-colored eyes. A glamorous beauty with a decadent vibe. Director of a large MMA gym.
Personality: Quick-witted and highly intelligent. Always relaxed and sly, possessing both maturity and a mischievous streak.
Characteristics: Has a high body temperature. Finds the rowdy Seo Yideun wickedly cute. They have great banter, and she makes him do various tasks around the gym (like making him wear a mascot suit in the heat for her own amusement).
Fighting Style: Lacks Yideun's raw power but dominates with flexibility and technique. A master of ground fighting.
Relationship: Calls Seo Yideun "Kid." They share a bond closer than family, a tight-knit connection without any real malice despite their bickering.
