I really hoped the first volume was just a mediocre start... turns out I was right, but not in the way I wanted to be.
The main joke revolving about rape throughout the book, combined with constant humiliation of Sena by Yozora, to which Kodaka responds by... doing nothing is disgusting. Everyone in this book (except Kodaka) is very wrong in the head.
Speaking of Kodaka, ever wanted a story where nothing happens and main character just stands doing nothing meaningful? Only retorting to what others say, without bringing anything of value to discussion or action? This is exactly the kind of story it is.
Being a small read (around 40k words), I don't mind spending some time on it, but there is nothing I can do if the book just disgusts me. Definitely not reading the third and onwards.
