Coming from a guy i think you should just be nice then be straight forward
If the guy doesn't have the guts to talk to you then you start talking to him about sports or something that you know that he might like to talk about.
just be yourself start a conversation
start saying ho to him. and smiling this will make him want to talk to you if he likes you back.
This might not really help you, but start by talking to him! Even a simple 'hi' will get him to start noticing you :)
start a conversation with him, see what you have in common
He likes you, obviously. You knew that!
It should start after you talk to the other guy.
tell him what you feel,dont be shy,dont talk to him so much or youll start to annoy him.
Just get his name or number, start to smile at him, and talk to him more.
Think of something you and the guy can talk about and starting to him but dont start off flirty.
well find some reason to start to talk to him
talk to them... maybe you will meet somone u like beter
