Some thoughts

I finished the novel from start to finish (I started in English but the translation was so awkward... as if someone just edited from MTL, so I just decided to read it natively in Japanese). I like that the manga actually adds on and creates new scenes to fill in the gaps of the novel. Of course, the novel is interesting because you get all the nitty gritty details of both Sibling's inner thoughts, but the manga helps to expand and visualize their world and give other characters perspectives too. There are so many new scenes in the manga that even as a novel reader, I get to look forward to what happens next, even if I know the ending.
