Wow, author really couldn't go more than one chapter without Aki and Shiho huh? Honestly this was a bait and switch manga. It was Shiho's manga the whole time. Hima and Yori were actually just side characters that started the story. Amazing. I already said why Aki and Shiho getting together makes them both look bad in the comments section of a previous chapter, so I'm not going to delve back into that, but holy shit this author just needs to be honest about who this manga is about.
