Advice?

So I’m 17 years old, I just started working, and there’s a man at my job who is also an employee but he makes me uncomfortable to the point where I feel nervous coming into work on my scheduled days. He looks like he’s in his early 30’s. Every time he sees me he’ll greet me with “Hi beautiful”, I didn’t think much of it. Another day, he asked me my age, I told him 17 and then he asked me when I’d be turning 18. Then he proceeded to tell me how cute I was and stuff. That was the first red flag for me. The other night when my manager wasn’t around he asked me if I was single and I really felt unsafe and uncomfortable. Am I looking too far into it or what should I do? I’m always trying to avoid him at work but he always find a way to talk to me and I hate it. I don’t wanna tell my parents or the manager yet because it might cause a lot of drama that I don’t want. I just want him to leave me alone though.
