Is this guy interested or is he just generally observant because he's found out I like him?

I ended up on the same shift as my crush. We haven’t worked together in 5 months. When I was going for my break my crush watched me walk out and I only noticed because someone called me from behind and when I turned back he was obviously staring from a distance.

The craziest thing I saw him come out after me 5 mins later and he made an excuse for someone to cover his work. So he only came out to observe me properly (usually I wear a face mask at work but on my break I took it off) literally the whole hour he was staring from a distance even when I looked up at him he didn’t break eye contact just staring with a straight face. Also when I got back on shift from my break he came in a few mins after me and pretended like nothing happened. I couldn’t believe that he went out his way to do that.
He has found out I fancy him through a work colleague and he knew he wasn't sure when he would see me again.
