Ok, this pairing is super stupid, I don't like the You/Riko at all, but dude, that doujin was good, probably because it could be any couple instead of this one in the story. It was very powerful.
Thanks for the translation and sorry for the beginning of my message that can put the wrong mood, but I don't like lying. It was cute, but it was not specially for me since i'm not into this pairing.
