What do you think of his reaction?

I met a guy at a party. We clicked at the first eye contact and then also while talking.
I saw him again at a party, he came to sit next to me on the sofa and we were almost stuck…talked for a long moment and sharing good vibes.

Once the moment to say goodbye came, we were a little group at the entrance of the residence, I started to say bye (kisses on cheeks) to people and he suddenly pulled back with a scared face. ?

how do you understand? Was he scared of a close contact?
