Why would you read what is essentially a hentai doujin with 24 pages and expects stellar writing and a moving love story?
I think it's because the author Ogino Jun had set a pretty high bar with his first series, Gamma, which did indeed have some amazing writing and not one but two well-written love stories. This is the reason why some readers, including me, were/are hoping for another story from him that combines an interesting setting and quirky but believable characters with lots of over-the-top action, postmodern references, and plain ol' sexiness just as well as Gamma did. Unfortunately for us (i.e. for people who expected more of the same), Ogino's most recent works increasingly focused on the sexiness part -- in his very particular lolicon yuri way -- to the exclusion of everything else.
While it is the indisputable right of every author to pursue the topics in their fiction that they want to explore, rather than what their (non-paying) readers want, I am still a little disappointed by the direction Ogino has apparently taken since 2015. I do have hope, however, that he is just taking a sabbatical after what must have been a rather stressful first major project for him, before returning to and improving upon his earlier style and work.
