There’s this guy I met at school and we were in the same class? I never got the chance to talk to him cause I was too nervous? I found his Instagram?

And I want to dm him. I don’t know what I should message him and ideas? I want to get to know him better cause it seems like we got a lot in common. I’d like to go out shopping with him to get to do something with him in person but I don't know if that’s too soon or much

What should I dm him? I was thinking about asking for #? Or is that too much
