@feha - Yeah, I have been reading both. I feel this one will end up being superior, as it looks like his editor at KADOKAWA is allowing some additional background details that are present in the novel, and to stretch out the development of the story a little bit. Like how it was mentioned that the furniture in the house was her mother's. It was a nice extra twist of the knife that I am sure was present in the novel.
I also like how the ex-fiance's selfishness and impulsiveness is slowly becoming exposed in this version. It gives a better impression that he didn't really think anything through and suddenly is forced to deal with the ramifications of his decision.
Of course, it doesn't hurt that this series is ongoing, and will likely go past the 10 chapters.
