People shouldnt notice

Meet Riley who is one of the few girls who actually loves learning new ways to defend herself...Yeah she is a fighter, a girl fighter. She is popular among the whole school.People steer clear of her ways because she has walls build up inside her head which no one dare break. What is her dark secret that she doesnt allow anyone to be near her?
Meet Brian, a nerd who loves keeping himself alone in his own world. He just moved to Granville .He is smart, funny and handsome behind his nerd glasses, then why is he so lonely? Is there a reason for him to not get noticed by others?
