I took me several years to finish reading this manga. The main reason I was attracted to it and kept going was the connection between the female and male leads. However nasty the story got, every time they were together there was such a soft and light atmosphere around them, I find it exceptional that the mangaka could create this distinct chemistry between her characters.
As a josei manga, this work explores two clear and mature topics: cheating and motherhood. The story itself is unapologetically sordid and overly dramatic especially towards the end. I think overall the mangaka does a good job in character development and in tying up everyone's story, but I personally felt things became too complicated in the last three volumes and I would have preferred more restraint.
All in all I would recommend this to people who are comfortable with these topics, not because I enjoyed the revenge aspect of it, but more for the character development. I think reflecting on the consequences of their decisions comes like an afterthought in this story but to me this should have been the main appeal, not the drama and scandal.
