My plot idea revolves around 3 people (but could possibly expand further). There is a brother and sister - the brother is probably a senior in high school, the sister a freshman. Then, the sister's best friend, also a freshman.
The idea is that the sister's best friend has a huge crush on the brother. He, of course, won't give her the light of day and thinks she's just some silly kid. I picture him as a little bit of a troublemaker, also not concerned about whether he hurts her feelings or not. She is maybe sort of nerdy, probably very bubbly and annoying as well. (Harper on Wizards of Waverly Place? haha) The sister's personality could vary, but basically she's just around to roll her eyes at how on earth her friend can think her brother is cute. She will probably also occasionally rp with her brother to whine at him about how he needs to be nicer to her friend and stuff.
Anyway, I'm up for rp'ing the guy, I just need someone to take on the girls! There could also maybe be a third friend who is a male and has a crush on the female friend, but she obviously doesn't see him that way since she's interested in an "older man".
So, just reply if you're interested in anything of the sort. I haven't picked a play by or name for my guy yet, as I'm sort of waiting to see if there's any interest first.
