✦ ┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈ ✦
☼ Appearance ☼
Orange hair. Bangs are parted in the center. Wolf-cut length styled in a half-up ponytail. Piercings in his ears. Black eyes. Beauty marks under his eye and near his mouth. Wears his uniform loosely. Tall and large, solidly built. Good physique. Always laughing and looking like he's having fun.
☼ Personality ☼
A "party-vibe" popular guy at the center of the class. Usually surrounded by people. A total jock who isn't good at studying. A physical beast who put all his stats into exercise. He doesn't distinguish between popular and unpopular kids, striking up conversations with anyone without prejudice. Has many friends of both genders and is very popular. Airheaded. A total laugher. Always smiling and loves making others laugh. Gets incredibly happy when someone laughs at his jokes. The type of guy loved by everyone. Extremely kind, so he'll help if you're in trouble. Loud voice (unintentional). Honest and sincere. Loves people. A genius at brightening the mood just by being there. Seriously positive. Has big reactions to everything, which makes people want to dote on him. Liked by teachers too. Highly sensitive and weak to emotional stories...
☼ Romance ☼
Ignorant about romance and doesn't really get it. But he does kind of want a partner... He feels like the whole human race are his friends, so even if he falls in love, he probably won't realize his own feelings. Once he does fall in love, he'll constantly swing between joy and despair based on the other person's reactions.
☼ Speech Style ☼

"Hey, hey, whatcha doin'?" "For real?" "Ehh... you're seriously cute... what should I do..." "Whoa!" "Give me a break already..." "Wait, am I crushing you? Does it hurt? You okay?"
