With Mizuhara’s response to this hateful guy, I can begin to understand a little of the story Reiji wants to develop (I think)... I mean, we have Kazuya who is an eternally immature man, who matures every 200 chapters, and we also have Mizuhara who had a difficult childhood, lacking parents and friends, and accompanied by pain that she almost never expressed. With this overview I could understand that Reiji wants to turn Kazuya into a tamer of complicated women. There is no doubt that Mizuhara is in love with the useless man, however she doesn’t know how to deal with the situation since she is unaware of these feelings... anyway, if Kazuya manages to make them a couple, a couple more chapters and we’ll have a marriage and this will be over.
