Hello there. No offense but it seems like you are making this story very rushed. Like you made Sato seem like a nice guy but you made him a dick in like two parts. You didn't make it feel like a it was that big of a deal, maybe if you gave him more time being a good person that plot twist would have been more drumatic. I'm just saying you are making a lot of story development in little parts(which is not necessarily a bad thing) maybe just add some filler chapters. I hope you take my feedback lightly. Hope you have a good day
