I myself would be concerned because Im a dude. But seriously in your case, I would want to find out right away if he was a total player, go up to him one time and say " So your officially the hottest guy at this school huh?" See if he laughs, or agrees, or humbly shys away. Your first impression of confidence and genuine inquizitiveness will have him thinking about you for a few days.
Oh by the way- if he just walks away from you without saying anything, he's a total douchebag.
