Most Helpful Girl
This happened to me too! I reckon he probably likes you, take it slow though... He'll probably start to show more obvious signs if he likes you after a while...
But I'd imagine he's into you! If he's making the effort to come and speak to you and to acknowledge you it can only be a good sign right?
When this happened to me I was really confused at first but the guy kept talking to me and make the effort to come and have a conversation and now we've been together nearly 4 months! So I'd definitely say it was possible!
Just be yourself and be confident with yourself and I'm sure he'll grow to love you! (If he doesn't he must be missing out on a great person)
Hope this helped! Good Luck
