Matsumoto Jun has built an empire on the back the world rejected and humiliated constantly on his sexual orientation. So he vowed to never hire a straight person in his life at his offices. They were ignorant, stereotypical and far too judgmental for the tastes of his magazine anyways.

And life had never been so idiotically hard for the bisexual god-gifted editor-in-chief since.
