besides the subpar ending (that had to be supplemented by text from the webnovel of how it would have ended), the story in general is wholesome. it really had an impactful beginning as the sisters were complementary to each other. However, when the internal conflict of staying or leaving this other world was being unraveled, it had fleeting and ungrounded feeling. Esp when it began to confront the romantic possibilities between Jade and Akane. "open ended" doesnt even cut it because the story fell flat just when a sort of climax is achieved between the two. there's a need for more chapters, or maybe even a volume to fully execute the story and at least match its strong beginning. (i'm not really one to appreciate being supplemented by the original text because it's supposed to be a manga adaptation... i don't like it when an adaptation is incomplete, where i'm seemingly forced to read the novel instead if I want to get the story.)
