This manga made me question the morality of incest. It made me question what kind of love is morally correct and what isn't . The art style isn't bad and I think the sexual scenes gradually lose their importance to the plot. I wouldve preferred having more of such scenes though. This manga does focus on the plot a lot and made me feel genuine disgust for the male protagonist a lot of times. The female protagonist isn't very unique in my opinion and i think some more insight into her childhood would have helped a lot with her character. The side characters were well written inmy opinion. However I would have enjoyed getting more insights into how the other characters view the relationship between the siblings in the story. Personally I found this work to be quite intriguing considering the siblings are blood related .
