Please help me !!!!

So one of my coworker always stares at whenever he sees me. Like when I was leaving the other day he turned around and looked at me. He has never talked to me, but yet we always seems to cross eyes with him each other. I’m 17 btw haha I’m not really good at catching hints when someone has a crush on me. Unless they tell me, I mean he’s cute but I don’t want to make assumptions and it might just be a coincidence 🤷🏻‍♀️. But idk he always looks at me and mostly at my eyes.
