Ogata is really a kid in the end. All this talk of 'black and white' is exactly what this manga is about, that you can't have right or wrong and it is often just as ambiguous as Satoko's words. This chapter is great because it portrays frustration teens go through when they grow older. Sooner or later Ogata had to face this shit, and she wasn't ready obviosuly. Tho very few are.
By the way, what's with your hands, translator-san? I hope it'll be fine 😘
