You're so right, but what I find funny is that in the most Yaoi there are just NONE at all! 95% of the people are male and oh! What a coincidence! They're all gay too!(⊙…⊙ )
The only girls that may appear are:
-The mother
-The antagonist
-Some girls at school to make you stop believing girls don't exist in this world
I always wondering WHY THE HECK ALL THE GIRLS IN YAOI IS A BITCH? And ANNOYING?
Lol. ( ̄∇ ̄") Like the Girl is Scarlet Scarlet ╮( ̄▽ ̄)╭
PS. Not at all (๑•ㅂ•)و✧
