Is this guy coworker just being a friendly guy or there is something more I just don’t really see it?

He always says good morning to me and asks how I am, he will have small chats with me occasionally or sometimes long conversations, his friends supposedly know about him bc he will mention his name and ask about him, he will stare at me constantly, always asks me for gum, always says my name when passes by and literally always has his eyes on me ( not sure if he is just watching me if I’m working) etc is he just friendly?
