How do I win him over?

Valeria

A few days ago I made a post talking about the guy this is about but basically we flirted a lot last time we met and today I'm having lunch with him and then another friend is joining us. I just need tips on what kinda stuff guys like: clothing items, way of speech, how to flirt blah blah blah anything you can come up with would be amazing I really just want to see if this could go anywhere. Thanks<3
