My Friends Describe Him So Much That I Find Him Interesting

So there’s this guy who works with me that I might have a little crush on but I’ve never really met him. I’ve heard about him so much from my co workers that I find him really interesting. We work in a hospital but two different departments and on two different shifts so when he comes I’m gone.

Last week I decided to go in on my day off and this guy walked pass me and spoke just to be polite. I glanced up and he looked just like the guy they were describing to me. So once my shift was over I went over to where I usually work and he was there. Again we didn’t talk but I had the feeling that he was watching me. My co worker later confirmed that it was him. I’m gonna be working that shift a lot soon so I wanted to know if you were in my position would you say something or just leave it alone since you could be working together soon?
