I always thought school days is the worst thing I'm going to experience in terms of "entertainment" It was dumpster fire of the decade for me. Sure many bad stories exist and I'd argue even the worst literature form has some sort of quality that author had mindset and they failed to execute those idea or it simply wasn't good enough to appeal mass audience but this manga.
I don't even know where to start and why the fuck this shit exist, like Holy fuck lmao. I never seen NTR done so bad and yes, I know NTR are trash to begin with but this takes whole new level of dumpster fire. I could write a long essay and dissect each moron in this god forsaken manga but fuck that, it would be waste of my time and it physically hurts me just reading this trash. Maybe translation is trash or this manga is trash or maybe both are trash?
TLDR: Fuck this manga.
