Why does this guy who only follows blonde skinny women on insta have a crush on me?

He constantly takes glances when he thinks I’m not looking and his friend confirmed that he was crushing on me. But when I checked his Instagram account almost every girl he followed were blond models and actresses and even random girls in his area. If I’m not his type at all why does he like me?
