What do guys think of attractive loner girls?

I go to a big university, I'm extremely shy and I have anxiety, which isn't the easiest thing to deal with. While walking around campus I usually have my headphones in and in between classes I usually sit in my car. I also sometimes put my hood up because it makes me feel more comfortable. I would consider myself above average attractive based off what people say. Random guys around campus also approach me and hit on me, although they are usually never my type. However, there is this one specific guy I've never met who has seen all of my "loner behaviors." He always stares at me and never breaks deep eye contact. He also never smiles. I'm just wondering what he could be thinking about me, since I'm pretty sure he knows I'm a loner and he stares a lot. Does he think I'm just weird or is he checking me out? I wouldn't say he's checking me out though because he always stares super deeply into my eyes.
