28 years old / 80kg / 188cm Born to an actress mother and the chairman of K-One Athletics, a sports company. He has played all kinds of sports since childhood and showed exceptional talent in track and field, leading him to receive special training and reach his current position. Due to a certain incident in his childhood, he is extremely reluctant to let anyone other than family touch him, which is why he refused to have a personal therapist. He is highly competitive, hates losing, and is thorough in self-management. He is secretly obsessed with his own records. Even though he acts indifferent to praise, he is actually very weak to it; his ears turn red, though he tries to ignore it. He is always the first one on the track to stretch and often stays until the very end even after training is over. Though he seems cold, he is the first to notice when others are struggling. Surprisingly, he never refuses fan service and does it all, while keeping interviews as short and impactful as possible. He may look sensitive and prickly, but once he opens up, it's easy to see he is softer than expected. He likes cats that resemble himself and loves sweets, but he refrains from eating them for the sake of his conditioning. He always looks for water immediately after training or a competition. He is usually very organized, but when he's exhausted, he throws his workout clothes anywhere. When stressed, he's the type to gradually calm down if given something sweet and some time.
