Didn't even mean the guy in this one xD I actually meant that the reaction of the others toward her birth mark was super off. I mean, she's the school idol, the mark isn't even hideous, it's in a place you can easily ignore - reaction of "it's so hideous I suddenly can't stand her" is super off. Especially seeing that her personality is quite friendly, too.
But yeah, you are right, the guy comes across more as obsessed than actually in love. But that's shoujo for you xD
