This manga is a genuinely heartbreaking read with a really good twist as a premise.
Story: While the story isn't overly complicated, the pacing and refinement is top notch. The climax of the story is also ridiculously staggering, leaving a lot of emotions behind in the aftermath. There's nothing quite like this, being honest.
Art: The art is great for the most part, but there's a few weird anatomy issues in some panels that break the illusion of being immersed.
Characters: The interactions between characters is well done, and enjoyable. The only aspects I didn't quite enjoy was the ecchi, but I'm also glad it didn't devolve into a harem.
This manga has a climax that genuinely leaves behind a lot of emotional baggage. It would be a shame to miss out on this series, solely for that reason.
