At this point I just think that the author got bored and wanted to finish the series quickly because this is one of worst character development I've seen in a looong time. I know I shouldn't except something from this type of mangas, but damn this is bad. Hopefully he get a writer for his futurs works because even if his art is good, he's pretty bad at writing from what I've read in this mangas and the "My New Wife is Forcing Herself to Smile"
