I feel like someone already asked this, but here goes, why all the girls doesn't mind being apart of a harem for Issei. I understand Rias, Akeno, Ravel and Koneko being cool with it because they are Devils/FA so they are used to the idea. But the others are humans or born as one before changing. So why are they okay with sharing him as most girls will hate the idea, as School Days shows.
