From what I saw in chapter 11. We see that the translation shows an opinion regarding his personality. I don’t wanna say I disagree or agree but I believe the issue doesn’t fall for the victim in the case. Even the sister has a hand in it then that shows that the sister must be insane to consider her parents acts as her brother acts as well. I want to believe that this manga will end in a situation with a happy ending but it doesn’t seem so. The main guy has a good and happy life, it’s insane to think he will be punished….
