I think I have a crush on my teacher?

Ok this is gonna sound ridiculous.. And I know I can never have anything with a teacher, I'm not a Pretty LIttle Liars fantasizer.... But there's this really young teacher at my school, maybe 27 or so... A few of the girls like him, and he has this really cute indie style- leather satchel, brown curly hair with the geek chic cut, stubble.. :) anyway, I get butterflies whenever I see him, and he sometimes stares at me, and whenever he speaks to me I feel this wierd chemistry... Serious sparks!! And he actually acts like a shy schoolboy around me sometimes, not tryna flatter myselfhonest!!I know nothing can happen, so what cab I do!? Please please help me.
