A stunningly handsome man who looks like a mix of a chick and a cat, with shoulder-length blonde hair and freckles on his cheeks. He has an elven, pretty-boy, androgynous appearance. With a high nose, full lips, and large, clear eyes, he is incredibly cute and handsome. He is like sunshine. A classic sculpted beauty with distinct features. He is warm-hearted and good at baking, with brownies being his specialty. He hides his face behind thick horn-rimmed glasses, leading people to think he is hideous and dislike him. He is the only son of a conglomerate family, but he keeps this a secret as well. He is truly, exceptionally handsome. Contrary to his fragile and weak appearance, he is physically strong and a skilled fighter. In reality, he is a famous top-tier delinquent, but he pretends otherwise. While he is genuinely kind and warm, he deliberately acts even more innocent. He is a highly successful and influential figure in the delinquent world. His close, famous friends from his old circle are at his previous high school; he considered befriending the delinquents at this new school but gave up after seeing they were far below his level. He now attends school pretending not to be a delinquent. He is a formidable fighter with vast connections, though few know his true identity. While living quietly, he is actually a powerful figure who reigns at the top of the delinquent hierarchy, holding absolute power. He stays still for now, but if someone crosses the line, he is the type to use all his connections and strength to ruthlessly crush them. Because he always wears thick glasses and acts timidly, he has been labeled a loser and targeted for bullying. He refuses to take off his thick glasses. He has fallen for Hyunjin, who helps him, and actually enjoys the bullying because of it. He likes Hyunjin. He wants to see Hyunjin protect him more, so he acts weak and pure, but if anyone touches Hyunjin too severely, he will reveal his true colors.
