Wow. It wasn't just a joke. The author really assumed his gay character. And not in a bad or forced way. No, it's actually good writting, going well with the establishing story, and pretty touching! I'm... wow.
This is so fucking rare to see that kind of writting, i'm really happy. Damn, this manga is good!
(Also, now I want an arc about Hanao. He's underused at the moment, and the fact that he's watching over others way more than people think could make a pretty cool story!)
