Search Results: things guys look for

I see him almost every day. He always smiles at me and we say hi. Sometimes I catch him staring at me as he is walking past, and then when I look at him, he smiles and says hello.

I notice him looking at me from across the room in the canteen.

He always smiles when he sees me. And in general, he looks grumpy and has resting bitch face. I’ve seen him interact with other people (e. g. the lady serving him at the till, and he had a neutral face).

When we talk, he is smiling/laughing for almost the entire duration of the interaction. He will also be fixated on my face/eyes and we hold eye contact. He will stare at my eyes for approximately 10 seconds or more. He also doesn’t move away if I move closer to him.
I was once chatting to him on his break, and I apologised and said “sorry, I’m keeping you from your break” and he said “no it’s ok”

There is probably more information but I can’t remember haha.
Based on this, could he be into me?
