Is it possible that this guy at work likes me?

There is a guy at work I felt was “rude” because he would never greet me or barley look my way. But then a few weeks later, of all sudden he comes up to me and asks to borrow something of mine I said ok and he leans into me so so fricken close like he was just millimeters away from me, I was so surprised he got all close when he haven’t even looked my way. Then he comes up to me again and does the exact same thing! He comes by and asks if I’m doing well and also wants to know what my plans are for this year. Now I catch him staring at me a lot and he is super nice to me. I don’t get it where did this come from? And why did he make an excuse to get so close to me? It’s risky in my opinion, he really saw his chance and took it.
