Guys, because of what happened involving the protagonist's ex-girlfriend and because it bothered me, I went looking for the raw Japanese version and in chapter 52.1 the protagonist appears and saves both of them. The thing is, the blond guy was about to hit Ichinos' girlfriend when he arrived at the last second... but honestly, that chapter about the sexual abuse of the ex-girlfriend was too much. Even though she's a jerk, she didn't deserve that, and the level of punishment was greater than expected. I don't know what happened to the author after volume 2; it seems like a completely different manga, and much darker. I'm only following it to see how the events unfold and to see the blond guy pay for what he did.
