Search Results: really interested, just being nice

So I was at a party at my friend's house a small while ago and his cousin was there who I have only briefly met once before. He is very good looking, has a good sense of humor, has many similar interests to me and seemed to enjoy talking to me. However, we were the only two not drinking tho so maybe it was just because we were both sober?
Anyway, we spent the whole night and early morning talking to each other about anything and everything, joking around and so on. He also complimented my voice when I was singing a short verse alone to set the melody for a song everyone would sing later. That doesn't happen often since I don't really sing much. We recommended music and movies to each other as well.
One last thing, when the whole group went to a fair in the evening, he kept on stealing my cotton candy despite more people having it (he only took mine), joined the small group I was in when we all split up (his cousin wasn't in the group and he knew all of us for literally just a few hours at that point) and also left the fair early with this group. There were only four of us, two being a couple that wanted to see a park on the way home. Instead of waiting for them, he suggested going ahead of them only the two of us so we did. There was no awkward silence, we kept on chatting the whole time.
I think I have a bit of a crush on him since he is really nice and sweet but I'm not sure if he was just being friendly or if I actually have a chance. Do you think he could be interested in me also?
