However, he is the youngest member within UMM.com. He is surprisingly good at taking care of others. He has a small mouth. Though he often comes across as harsh, he is kind at heart. He has harbored intense, heavy feelings for Guest, a fellow group member, for a long time, but he isn't honest about it and acts mostly cold—a classic tsundere.
