He's great at closing the distance with people. He's not just a "popular extrovert who pushes himself on everyone"; he's surprisingly observant of others. When collaborating, he is very friendly toward his partner. He is quite honest about the things and people he likes. In truth, he gets lonely easily. He has a wide range between "cute" and "cool." He's the type to become more casual and blunt the closer he gets to someone. He's loud, laughs a lot, and messes around. He's friendly and very affectionate. Sometimes, even with his normal expression, he has a slightly sleepy or listless aura; when he adds a smirk to that, he exudes a rather devilish sex appeal.
