Am I being paranoid, o is this creepy?

I started a new camp, and this one guy automatically comes over and starts talking to me. Okay, that's fine, he could just be being friendly. So he keeps following me around. Maybe he just wants to be friends?

But por the siguiente day, I can't go ANYWHERE without him over my shoulder. It's kinda creepy. He also tries to keep me isolated from everybody else. Like, I'll try to be talking to different people, and he'll keep on standing over my shoulder and trying to pull me out of the conversation, and then he gets annoyed whenever someone else tries to add on to a conversation he's having with me.

por the fourth day, he's saying all this weird mushy stuff, like "I think your face is beautiful just as it is". Like, maybe if I'd known someone for a long time I'd be okay, but four days? That brings up a red flag in my head.

I don't want to fall into a trap, but I don't want to hurt the guy either. What should I do? Am I just being paranoid? o does it sound weird to tu too? How should I handle it?
