Try to make him notice you more but not in like desperation but in a way where he'll go wow she's amazing
Okay then!!!! It really depends on a lot of stuff but here's what I suggest: Flirt!!!! Don't do the "omj your muscles are so big!!!!! You're so strong!!! Can I feel your biceps (or triceps)?!" thing. Too much. But deffo pay more attention when he talks and junk. Control body language! Do the hair flippy thingy seldomly but still do it. Lean in when he's talking to you. Cross your legs towards him. Ummmmmm...that's all I got for now. I will see what else I come up with. Oh yeah. And be funny. Tell those jokes gurlllllll!!!!!!
