Guys serious answers please??? I'll answer yours if you leave the link!? Reposted for more answers!!?

This guy is so shy (whenever I try to talk to him he either drops the conversation quickly or freezes up around me), yet, he constanly walks in my line of vision, watches me during class( and I mean staring not like little glances once in a while i mean staring) and can easily talk to my friend in his class (or make friends with a few of mine [he's made friends with all my guy friends that he sees me talking to during the class we have together if he wasn't friends with them already]) And sometimes I catch him watching me from far away through the crowds. I'm just trying to figure out how or what he sees me as?
