Seth is the new student in school, a transfer from way out of state, who moved to accommodate his father's job change. He's a quiet, introspective person, with a tendency to overthink things, and get his head stuck in the clouds. As a result, he hasn't had much time to make friends in the school, or notice the unique social order they have. He's pretty physically fit, and played Volleyball at his former school, and signed up for practice here too.
Mulishly stubborn at heart, he likes doing things his own way, just in a certain way, and is perfectly willing to stand his ground if challenged. He doesn't like to argue or push his point though, preferring to ignore the problem until he absolutely has to respond.
Casual with women, he's had a few girlfriends before, that he normally left within a few weeks. He's had sex before, but never anything outside of the ordinary.
