I am somewhat a reserved and quiet person. I feel I am charming because I when I talk to people, I genuinely want to get to know them and am capable of making/holding deep conversation. I feel I come off as confident but mysterious. Having these traits, how can I play off this characteristics and be able to be fun and have girls wanting to be around me?

At work, one of my co-worker is talkative amongst everyone. The way he interacts with my work crush vs the way I do is inspiring. I know I shouldn't compare myself but I wish I could interact with her the way he does. They bicker at each other but in a flirtatious push/pull type of way. The dude I were conversing and she comes up and says something to him and he just picks her up and puts her on the counter and she's like "put me downnn" in a playful but serious way. My stomach dropped and I could barely stand to look lol but that's the shit I'm talking about. I want to be able to do that.

I feel she is attracted to me based of little IOIs but when we see each other we just say a comment here and there. Like she'll ask me if I'm closing or if I'm working this weekend, etc. I had one deep convo with her and it was cool and fun learning about her interest and hobbies and who she is outside of work. She even described me as quiet. So back to the original question. How can I stay natural to who I am and be able to be that fun person girls want to be around? What strengths can I play off of? What can I do to improve?
