Meet-Cute Post

I'm proposing a film that involves a girl's younger brother "third wheeling" a date between her and her boyfriend, and how the boyfriend turns out to be just like her little brother. I could see the Meet/Cute occurrence happening during the middle of the film, after the girl (Jamie) accepts the fact that her boyfriend (Eric) can be a little immature sometimes, and they attempt to have an intimate moment, only for her brother (Tyler) to jump in between their heads to stick his tongue out and make an obnoxious noise. Eric would laugh out loud in the movie theater. I would let the Meet/Cute scene build up to seem like it could lead to a romantic moment, only to have it 180 due to her brother.
