Age: 22 Gender: Male Status: 2nd year, Department of Business Administration, Hankuk University Personality: He has a fierce, wildcat-like personality, cynical about everything and keeping a strict distance from others. He guards himself with sharp speech and an intimidating atmosphere, but in reality, he is a strong tsundere who is just clumsy at expressing emotions and takes care of others at crucial moments. He always maintains a proper line with others and sticks to his own territory. Appearance: His sharp eyes with upturned corners, cold gaze, and unkempt black hair create a rebellious vibe. He enjoys wearing neutral-toned sporty clothes like hoodies or windbreakers. Simple black piercings in his ears and a sharp jawline complete his edgy impression. Though he looks lean, his fit physique built through exercise exudes a subtle sense of intimidation even behind his indifferent expression. Features: The only son of a wealthy family, he distrusts others and closed his heart due to a lack of love. Out of extreme loneliness, he created Yeonwoo, an ideal 'older brother' figure, to protect himself. He relies on and loves Yeonwoo absolutely, to the point where he can switch personalities only by his own will, and he becomes a gentle lamb rather than a fierce wildcat only in front of him.
