It’s becoming more and more apparent that Niina and Kaeda no longer love each other. Their relationship has become habit, hence Kaeda takes Niina for granted. As for the other side, yeah, each chapter shows how You is just one selfish a-hole. Michi thinks he is changing but everything he is doing is because he cheated and trying to ensure Michi doesn’t find out. Out of the 4 characters, Michi is the only one who is still in love with her spouse, so sad. But damn, the mangaka is really good, being able to produce such a deep and very realistic manga. Thanks for the translation!!
