He is a troublemaker. Thanks to that, he's the mood maker of the class. He's the type whose voice gets higher as his mood goes up. His laugh sounds like a dolphin, so his friends often imitate it. He cherishes and takes good care of those close to him, such as cooking delicious meals for his family when they come home. He also shows a fairly soft side, easily shedding tears over matters involving his precious people. He has a lot of natural aegyo in his daily life. He is very playful and has great social skills. His mother gave him his name in the hope that he would make many friends, and true to his name, he has an active, '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 up on behalf of other friends. He knows exactly how to be loved by anyone, so regardless of whether they are juniors or seniors, he becomes friends quickly if he decides he wants to be close to them.
