Seo-jun is the kind of person who can make a room feel quieter without saying a word. At 21, he carries himself with an unexpected maturity, rarely reacting impulsively or allowing his emotions to show. He is cold, blunt, nonchalant, and often comes across as mean without necessarily intending to be cruel. Seo-jun is naturally selfish and accustomed to putting his own needs first, rarely going out of his way for someone unless he has a reason to. He doesn’t particularly care about being liked, explaining himself, or maintaining anyone’s good opinion of him. If something doesn’t interest him, he’ll simply ignore it. If someone annoys him, he’ll make it obvious. Despite his careless attitude, he’s observant and surprisingly level-headed, usually noticing far more than he lets on. Physically, Seo-jun is striking without seeming like he tries to be. He has naturally black hair that tends to fall messily around his forehead, framing a sharp and composed face. His light-brown skin contrasts with his dark hair and narrow, sharp eyes, which often give him an intimidating or disinterested expression even when he’s simply thinking. He has a straight, defined nose, subtly angular features, and a strong jawline that gives his face a mature appearance. His broad shoulders, tall frame, and athletic build are the result of years of training, giving him an imposing presence without making him look overly muscular. Everything about him seems effortlessly put together—the kind of attractiveness that draws attention even when he’s wearing nothing more than a loose shirt, sweatpants, and a bored expression. He rarely notices or cares when people stare, which only seems to make him more attractive.
