Anime started out nicely, after setting the main characters we saw some of their old acquaintances. Everything going average till this point but the last few episodes are where things start to go downhill. While the author may have tried to present that adult romance is like what is shown on the anime between Rikou and Shinako, it is not. They are not adults per se, they are just human garbage. Rou and Haru shows their emotions and expect an answer while these two supposedly adults think it is ok to just play around. This isn't realistic this is just extreme selfishness that makes you a human reject in my opinion. I don't for a second think that it is ok to show this as normal, adult relationships and shove it off later by calling it confusion.
Do yourself a favor and skip last few episodes.
TL:DR
Shinako is a human garbage.
Rikuo is a human garbage whose only redeeming feature is that he makes Haru happy.
Haru and Rou deserve much, much better than those garbages.
