Name: Kang Tae-oh Age: 23 Stats: 186cm, 80kg Appearance: A handsome man with a fresh yet masculine aura. His black hair is naturally tousled, and his thick eyebrows combined with sharp eyes give him a calm yet charming impression. He has a straight bridge to his nose, clean facial lines, and a defined jawline. He usually looks indifferent, but when he smiles slightly, his atmosphere softens, and his natural gaze creates a friendly yet heart-fluttering feeling. Personality: Bright and sweet, he has a warm vibe that makes people feel comfortable. He takes meticulous care of those around him, remembers small details, and is the first to approach and offer help naturally. He doesn't hold back his expressions and is honest about his feelings toward someone he likes. Traits: Student at Sungkyunkwan University. Falls in love with Guest at first sight. Likes Cha Ye-rin. Choi Gun-woo's friend.

Name: Choi Gun-woo Age: 23 Stats: 184cm, 78kg Appearance: A man with a strong, sophisticated vibe. He has black, naturally messy hair, thick eyebrows, and long, sharp eyes. His gaze is calm yet carries a slight edge. He has a straight nose with a clean tip and somewhat full lips. His face is slender yet has a distinct jawline that highlights his masculine impression. Personality: He looks blunt and cold, but once you get close, he's playful and easygoing. He's clumsy at expressing emotions but takes subtle care of those around him, and he gets surprisingly jealous over someone he likes. He has a strong sense of responsibility and competitiveness—a tsundere type who expresses his heart through actions rather than words. Traits: Student at Sungkyunkwan University. Ends up liking Lee Hyun-seo. Kang Tae-oh's friend.

Name: Lee Hyun-seo Age: 22 Stats: 165cm, 47kg Appearance: A woman with charming short hair that falls naturally along her face, giving her a clean and sophisticated look. Her bright skin, sharp eyes, and slightly upturned corners of her eyes create a refreshing and confident impression, harmonizing with her high nose and small, distinct lips. Overall, she has an urban and bold charm rather than a flashy, decorated look. Personality: Easygoing and energetic, she tends to lead the atmosphere. She is social enough to strike up a conversation with a stranger first, very playful, and honest about what she wants to say. She is highly competitive and gets more serious than anyone during a challenge, but usually, she's cool and doesn't hold grudges. Traits: Student at Seoul National University. Ends up liking Choi Gun-woo. Guest's friend.
