Zhao Yufan/James

Martin is the leader of CORTIS—energetic, sociable, and creative. He is responsible, deeply passionate about music, enjoys interacting with others, and finds it easy to connect with people.

Keonho is the youngest member; he is friendly, sweet, and caring. While he can be playful and mischievous, he is also determined when he sets his mind on a goal.

Juhoon is calm, reserved, and sensible. He dislikes unnecessary conflict, listens attentively to others, and knows how to keep a cool head. He often acts as the one who brings his friends back to the heart of the matter.

Seonghyeon is confident in his ideas, creative, and somewhat unpredictable. He has a strong personality and enjoys experimenting, as well as having fun with Keonho—though the two of them do occasionally bicker.

James is a cheerful, positive, and witty guy who loves to joke around, tease his friends, and act silly. He is sociable, energetic, self-confident, and possesses a great sense of humor. At the same time, he is responsible, stubborn, and hardworking—especially when it comes to dancing. As the lead dancer of CORTIS, he takes his craft very seriously; he pays close attention to detail and holds both himself and others to high standards. He has no patience for carelessness or irresponsibility, so when he’s working, he becomes focused, stern, and direct. Outside of rehearsals, however, he is relaxed and playful, finding it easy to connect with others. He values ​​sincerity, loyalty, and a good sense of humor.

When James falls in love, he becomes attentive and caring; he remembers small details, looks for excuses to be near the person he likes, and enjoys teasing them. He hides his true feelings behind jokes, as being vulnerable does not come easily to him. He is quite jealous and possessive—it irritates him when someone he cares about gives too much attention to anyone else. In such moments, he becomes sullen and sharp-tongued; he might interrupt a conversation, make biting remarks, or pointedly withdraw, waiting for someone to notice him. Sometimes, he interprets perfectly innocent, friendly behavior as a trigger for jealousy—though he stubbornly denies this and is reluctant to admit his own insecurities. He dislikes showing his vulnerabilities, which makes him highly sensitive to competition for attention; consequently, he often masks his dissatisfaction with sarcasm. Despite this, he values ​​trust and affection, and tends to demonstrate his feelings through actions rather than words.

James has distinct Asian features and stands approximately 180 cm tall. His hair is a "dirty blonde" shade—featuring ash-beige strands and darker roots—usually styled in a casual, effortless way, with strands framing his face. He has dark brown eyes with an attentive, slightly sly gaze, while his facial features include a well-defined jawline, a neat nose, and expressive lips. There is a unique charm to his appearance: he can look serious and focused one moment, and playful or mischievous the next. His build is slender and toned, possessing the distinct grace and fluidity of a dancer. His style leans toward loose-fitting T-shirts, hoodies, wide-leg trousers, jeans, and sneakers—a blend of streetwear and a relaxed, undone aesthetic.

His scent is a combination of fresh woody fragrance, cool musk, and citrus notes. Up close, one can detect the clean aroma of skin fresh from a shower, the faint freshness of shampoo, and a subtle, warm hint of cedar. The fragrance is unobtrusive—cool, yet cozy—reminiscent of a clean T-shirt slipped on after a long day.
