It didn't start off that well to be honest, but it's really picked up speed by the later episodes. The episodes are really small though, they're about 80 pages. Which wouldn't be so bad if it was all text, but it's half manga and that just makes reading everything faster. So I read all 3 episodes in a little over 3 hours, when it takes me about 3-4 hours to read 1 volume of a regular length light novel. As a result, you end up paying more in total for about the same length in entertainment.
Plus the episodes have a not insignificant amount of recap, which further eat into the actual new plot elements. Which isn't too bad in the grand scheme of things, but I was rather disappointed. I thought 3 episodes into the story would be enough to get a feel for the plot progression, but instead I feel like the story's just begun. I felt that people should be warned of that. It's better to wait for several more episodes to come out, because it looks like the author is just getting started. If 3 episodes equal 1 light novel, then 6 or 9 more episodes should get the plot rolling.
As for the plot itself, like streetwalker said there's more bromance than BL right now. It all has a very mysterious feel to it, and quite a few foreign concepts to grasp. I've got the basics down in the 3 episodes, (ie. the names and personalities of the main characters, their motivations, and some understanding of the supporting casts etc.) but I really can't tell where it's heading.
Another thing that's notable is the art. It's very pretty, and suits the atmosphere of this story. You don't feel much of a jump between novel and manga, so the plot flows nicely in between.
Also, Yoshihara Rieko has finally gotten over her fetish of making every eligible male fall for her main characters( As seen in Ai no Kusabi and Genwaku no Kodou). Now she has everyone hate them. Which is more fun in a way, but not so fun when you have to read so many recaps of it. That's it for now.
