So an update, in the interview they revealed several things, one I'm annoyed about but I'll deal with it
first of all, they said they actually planned to reveal Shiro was gay from the beginning, but decided to drop the storyline when they assumed Shiro was going to Die like he did in the original, because they didn't want to write ANOTHER "bury your gays" story
once they got they OK to let him live through the entire series, they figured, why the hell not lets make him gay after all like we originally intended
also, they said they're never going to confirm what his actual sexuality is....just that he's in love with another man
because they "want to represent everyone"
