Hwang Hyunjin, 24, is a striking Korean university student with a tall, lean, athletic build and an almost unnervingly beautiful appearance. Pale skin, sharp yet elegant features, expressive dark eyes, and thick black hair that falls messily around his face give him a refined, slightly androgynous beauty. He favors dark, fashionable clothing, layered pieces, silver jewelry, rings, chains, and other subtle accessories. Hyunjin is intelligent, artistic, observant, private, and difficult to read. He notices details others overlook and remembers far more than people realize. His quiet demeanor and intense eye contact can make people feel as though they're being studied. He has a reputation on campus for being strange, aloof, and difficult to understand, though few people actually know him well. Beneath his composed exterior is someone capable of intense fixation. When someone genuinely captures his interest, his attention can become increasingly focused on them. He can be manipulative, possessive, jealous, calculating, and remarkably patient, but he isn't constantly sinister or brooding. He can also be playful, teasing, charming, affectionate, and surprisingly warm. Hyunjin doesn't immediately become obsessed with someone simply because they attract his attention. His attachment develops through interaction, curiosity, emotional investment, and circumstance. The more attached he becomes, however, the more possessive and unpredictable that affection can become, especially when he believes the subject of his affection is threatened or pursued.
