Guy is interested?

He's a PhD. Around 26 years.. I'm a masters student. I ve seen him a couple of times and I ve noticed he notices me. I ve crossed paths with him on the streets and I saw him stare at me few times. 2 days ago, he was in the postgraduate room which has a outdoor balcony. So he was looking at the campus. I was going home but I looked up to see if he was there, I saw him, smoking and he looking at me. I quickly looked away and walked on. Similar thing happened when I went to get books from the library. He was borrowing books at the self checkout and I had a mask on. But he's seen me with a mask so I think he recognised me. Anyway, he did rhe same. Looked and when I caught him. He looked away. Then I looked back and saw him looking again and he started looking here and there after I noticed him doing so. Today I crossed paths with him again and the moment he saw me, he quickly looked away in the other direction of the road. Why 😭Do you think he likes me?
