well my bf goes to a different skool than me it can kinda be hard at times. so we dont get to see ech other every giorno but i talk to him til lik right when i get out til lik 11 at night. u could maybe ask ur friend to ask him his number if e has a fone and just talk to him and mostra him wat ur lik thats wat happened with my bf, he's my friend's friend and i just took her fone and started texting him and then he ended up liking me so I WISH U LUCK!
Maybe just try hanging out with him! If he doesn't like te for u, then he's noott worth it! So yeah, just hang out with him, see what he likes to do, what u have in common.. Things like that :) Hope I helped! and good luck :) :)
