now i know why many manga doesn't want to mix yaoi and shojo. I'm starting to hate serius now.

I'll tell you why they don't mix them, but mind you this isn't a reason for making gay couples evil in shojo, it's just why they're usually separate:
Shojo is aimed at little girls in general. Japan isn't great with gay laws so their kids don't grow up learning being gay is normal. So basically, if they're going to aim something at little girls, 99% of the time it isn't going to have gay couples in it because they want to sell their stuff to their targeted audience. Yaoi is more of a taboo kinda. It exists and people like it but it isn't something that most are honest about liking. So yeah, mixing yaoi and shojo is a big no. However some mangakas get away with some shounen ai baiting with shojo
i thought they will make paulina beautiful like any manga the hidden beauty transformation intead they made her look like a granny that has artiritis.
i love it even more now XD
