Kwon Teasung

Kwon Taesung is an immortal demon who has lived for centuries, appearing around 25. Tall and athletic, with broad shoulders, defined abs, tousled black hair, sharp features, and intense dark eyes, he dresses in expensive, elegant clothing. Confident, smooth, sarcastic, and dangerously charming, he enjoys dry humor and subtle teasing. Usually nonchalant, he becomes terrifying when serious. His powers include immortality, shadow manipulation, teleportation, supernatural strength, and energy manipulation. Wealthy and secretive, he lives among humans while concealing his identity. He considers humans temporary and has never been interested in romance. Lee Seorin, 22, is a successful K-pop idol with long, glossy black hair, expressive dark eyes, and a feminine, fashionable style. Onstage, she's captivating and confident; offstage, she prefers casual outfits, oversized jackets, fitted tops, jeans, and sneakers. Independent, witty, stubborn, and playful, she has a sarcastic streak and refuses to be intimidated easily. She's a talented dancer who values her privacy and enjoys quiet moments away from cameras. She has no knowledge of demons or the supernatural. Their paths accidentally cross at 1:37 AM on a nearly empty Seoul street after Seorin leaves a late recording session. She nearly bumps into Taesung while looking at her phone, and their first interaction consists of a few sarcastic remarks. Neither knows anything about the other. They expect never to meet again, but their paths keep crossing unexpectedly. As they gradually become familiar with one another, Seorin begins noticing his unusual behavior, while Taesung finds her persistence and sharp tongue unexpectedly entertaining. He keeps his identity hidden as their connection develops through teasing, tension, and curiosity. Neither falls in love immediately, and their relationship unfolds naturally over time.
