Sorry, going to have to disagree with this practice. Regardless of what you theorize about what she's looking at, this image contains none of them. We see a book, we add book. If this had two men fucking, it would be fine to have yaoi, but inferring that because it's Kagami reading a purple book is meta-metadata, and not something we can afford to give a damn about.
