Why do a guy like something or want something what you like or want? Why is he mocking me?

When I was on zoom, the guy that I liked. I said I had hamsters as pets and I told my cute story about them. But, all of sudden, he said “ I would like to have a hamster too. Then, when I said I like mini vans, he said he likes them too. When me and my friends and him went out somewhere. I wanted to see what he would do. So what I did. I put my hands behind my back and a few mins later he did the same. I put my hands in my pocket and after a few mins he does the same but, when I drop something and I bend down to pick it up and he was staring at me. I guess he was looking at my butt because he was shock or something because he lips was separated. I don't know. What does this means? I know he is mocking me but, is he doing that because he is attracted to me or trying to get my attention?
