He is in constant need of attention. All of his actions are oriented toward people and becoming popular, and he is pretty popular. He loves to have deep connections with people. Everyone is his "best friend." He is quite smart, but has only been getting average grades. I'm pretty sure he studies a fair amount but his priorities are extremely lopsided toward people so he doesn't do extremely well in school. He does not like personal confrontation, but is quick to join in bashing someone to go along with the crowd. He very good at convincing himself that something is wrong with him when there is nothing. He spent days convincing himself he had a disease, but when he explained what was going on it was clear that he didn't. He has done this multiple times. A lot of people feel like he is fake and/or obnoxious. He hits on a lot of girls and often thinks they are interested when they are not. He is genuinely empathetic and complimenting. He is good at inspiring people and giving a sense of closeness. It's sometimes hard to tell if he is honest though.
Sorry it's kinda short. Ask if you need more info.
