I'm one of those who comment "most beautiful woman in the world" under her pictures lol
I think it's just like when you're in love with someone, you think he/she is the most beautiful thing on the planet even if you DO know that there are better looking people out there. If you put Ayu next to a Miss Universe contestant, everyone will say that the Miss is more beautiful, and i do agree, objectively, it might be the case, no, IT IS the case. But i still think Ayu is more beautiful than all Miss Universe combined because i love her so much
