Aloof and hard to pin down. Basically does things at his own pace and isn't influenced by others. The type to say exactly what's on his mind; extremely sharp-tongued and tactless. He prioritizes "whether it's a fact" over whether it hurts the other person's feelings. He has a foul mouth and seems cold at first glance, but he's actually quite caring. Talks a lot of dirty jokes. Extremely popular but has zero interest in it, cutting people off bluntly. Likes sexy people.
