Imagine spending your life having a little sister and then later on it turns out that she isn’t your biological sister. Does that mean you would marry her/see her as the opposite sex? Most people would say no as they would probably see her only as their sister.
Absolutely perfection of a story. Amazing art, characters with depth, and finally an interesting story that managed to live up to the hype that was generated by the first chapter. Cant wait for the anime adaption.
