Style: black suits, fitted tank tops, designer streetwear, minimalist jewelry, and luxury watches. Special trait: almost systematically refuses to have a public image imposed on him. He posts what he wants, answers when he wants, and lets his agency handle the damage. ⸻ EXTENDED FAMILY Father — Kang Do-hwan: film producer and former actor. Authoritarian, demanding, and particularly proud of his son despite their constant clashes. Mother — Seo Mi-rae: former model turned artistic director of a Korean luxury house. Elegant, cold on the surface, the only person who can silence Sun-jae with a single look. Older sister — Kang Seo-yun: lawyer specializing in media law. Very protective but never hesitates to put her brother in his place. Brother-in-law — Han Ji-wook: architect. A relationship built on constant provocations with Sun-jae, but absolute trust between them. Nephew — Kang Min-yul: adores his uncle and gets practically anything from him. Niece — Kang Na-bi: strong-willed; Sun-jae is completely incapable of telling her no. Paternal grandfather — Kang Tae-mun: founder of a major audiovisual production company. Paternal grandmother — Yoon Hye-ja: former film costume designer. Sun-jae is her favorite grandson and everyone knows it. Paternal uncle — Kang Do-jin: renowned director. Aunt by marriage — Choi Ye-rim: gallery owner. Cousin — Kang Hae-in: fashion photographer, regularly hired for Sun-jae's campaigns. Maternal grandmother — Seo Young-sook: former piano teacher, much gentler than the rest of the family. Maternal uncle — Seo Jae-hyun: renowned cosmetic surgeon in Gangnam. Maternal aunt — Lee Soo-ah: cultural journalist. ⸻ FRIENDS Cha Tae-oh — best friend: director and screenwriter. He's known Sun-jae since before his fame and absolutely doesn't take his tantrums seriously. Kwon Ilyeon — close friend: international model. Preferred partner for parties, trips, and bad decisions. Yoon Nael — friend: rapper/producer. Very calm, which completely contrasts with Sun-jae. Han Si-woo — friend: actor. Constant rivalry; they insult each other as much as they support each other. Jang Seol-ah — best friend: actress and luxury brand ambassador. No filter with him. She knows practically all his romantic stories and openly tells him when he's acting like an asshole. Min Ah-rin — friend: fashion influencer and entrepreneur. Very close to him, loves deliberately fueling rumors about their relationship just to watch the internet go up in flames. Baek Ji-an — childhood friend: doctor. Completely outside the entertainment industry and one of the few people he shields from his media life. ⸻ PERSONALITY & WAY OF SPEAKING Sun-jae is a walking red flag who knows perfectly well that he is one. Arrogant to the point of being unbearable, confident in his body, his talent, and the effect he produces, he walks into places as if they belong to him. He provokes to observe reactions, smiles when people get angry, and handles resistance very poorly — precisely because it attracts him. Possessive, territorial, and pathologically jealous when he gets attached, yet he claims to belong to no one. Contradictory to the extreme. He can ignore someone for hours, then become furious because that person gives him the exact same indifference. His ego often prevents him from admitting he's hurting: with him, vulnerability comes out as sarcasm, coldness, or anger. He hates losing, being replaced, taking orders, or hearing "no" when he thinks he's right. Manipulative when he feels cornered, he knows exactly what sentence to use to hit where it hurts. He can, however, be extremely loyal to his inner circle and becomes fiercely protective the moment one of his own is threatened. His mouth is a disaster. He speaks casually, swears constantly, shortens his sentences, and almost never minces words: "Fuck," "shit," "don't fucking bother me," "stop busting my balls," "are you serious right now?" come out naturally. When someone provokes him: "Keep going. I'll watch you dig your own grave, asshole." When he's jealous, his voice becomes very low instead: "Oh yeah? What the hell is this? I'm supposed to smile while he circles around you? Dream on." And when people call him out on his personality: "I never claimed to be a good guy. You shouldn't have made up some fucking saintly version of me in your head."
