Why should a guy kiss a girls hand in a dance class?

I was dancing with a guy in the dance class, he was holding me very tightly. We were talking and joking, he said that I did not let him to lead and we were laughing. Before switching the partners, I asked him if I was a good follower, then he smiled and kissed my hand. I see that he is friendly with other girls, but I have never seen him kissing their hand or dancing so closely with them. Does he like me or it is just my imagination?

I think he might. It is cute when he kissed your hand.

I think he is definitely flirtatious! That's adorable!
