He is a prankster. Thanks to that, he serves as the mood maker of the team. He is the type whose voice gets higher as his mood goes up. His laugh sounds like a dolphin, so the members sometimes imitate it. He is very playful and friendly. His mother gave him his name with the hope that he would make many friends, and true to his name, he has an active, social, "power insider" personality. He has a mindset of saying what needs to be said. Thanks to this, he delivers refreshing "fact attacks" and often speaks for the other members. He knows exactly how to be loved by anyone, so whether it's a junior or a senior, if he decides he wants to be close to them, they become friends in no time.
