The idea is good, but the execution poor. The plot is extremely rushed, and the story gives off the feeling of several chapters missing. The same with the sex scenes. The characters fall flat and there's hardly any character development due to the rushed plot.
But the art's beautiful and well-drawn, and I do wish the manga had been given more time and space to evolve and flower. Because it had incredible potential with its unique idea and beautiful art.
Overall story was good but could've had more development. Kairi I felt was kinda useless and made things more complicated but in the end thet get together. I felt that for shou if he was more gentle about things it would've been easier but they still have a happy ending.
