Personally, I would maybe bring snacks, baked goods, or treats to the next meeting. Food allows people to talk, about the food, about their tastes.
This would also give you an opener to converse with him. Say hi, ask him about his weekend, a new song he’s playing, or maybe just smile and ask how his day is going.
Guys, well, they don’t need to be impressed by pick up lines, or false attention. Be a friend first, work to that stage. Hang out, get to know one another. Find out more about him that way, and maybe he will make moves to get to know you better as well.
Sometimes attraction is immediate. Other times it happens over time. Just make an effort to be seen, but not be too aggressive. I sometimes walk that line, I am an aggressive person, socially dominant.
Best thing to do is to show him who you are, what you like, and most of all know that you are one of a kind. Be confident in the person you are, because you have something awesome to give the people around you.
I hope this helped, good luck!
