how to get a guy

so i like this guy that's older than me by half a year, he's majorly popular, and he's my brothers friends which sucks. i barely see him only in the halls at school, at my house at parties, and we've only talked like twice and it was like two words. the other time was when he was drunk and he basically cleared up this awkward encounter we had that i could tell was bothering him anyways not gonna get into that. So how do i become friends with him. he doesn't come around the house as much and he's kinda quiet when he does. also my brother and him haven't been friends long so i'm not that comfortable talking w/ him yet but i want to. also i'm pretty sure he has a crush on this super pretty girl he works with, at least we all know she likes him. anyways how to i get this hot ass guy to date me 😂😂

side not: what r my chances. i'm somewhere between ok- sorta but not really popular (mainly cuz everyone knows me as my brothers little sister) and he is one of the most popular guys at least in his grade if not the school. the dudes hot and well i'm average to below. i was rated once and i was a 6 if that helps at all. sorry this is long btw and BE HONEST PLZ i would just go ask my friends if i wanted lies 😂😂 thanks ! :)
