Guy's Behavior

I saw the guy In interested in looking at me for several seconds. We made eye contact I think. Was he looking through me or at me?

He was looking for several seconds before, and when we locked eyes it was maybe 4. I couldn’t read much emotion on his face, but his whole body was facing me and he was looking in my eyes (I think) before I looked away and I don’t know what happened with him after that. Honest opinions?

For updates, we are acquaintances in class (which just started) and hit it off but we don’t really know each other yet. This happened after day one of actually having conversations in class
