im such a sucker for mystery genre oh fuck, also yes i do agree to some of these ppl saying stuffs like "the rules are dumb" "ah yes a all girl's school about girls graduating js to marry men turns out to be full of lesbians". i agree w the first one. bu tthe second 50/50 bcs its not that uncommon to not find atleast 2 girls being a lesbian in a all girl's school, heck probably 30% of the students are lesbians.
okay back to the plot, i think this manga has a lot of potential if someone didnt js stopped mid way at a cliffhanger like this. some parts are predictable, but ig all stories has that. but hey, doesn't mean this series suck, while im reading this i couldn't stop my heart from racing bcs of the thrill in this series and god i love making theories w myself. so my brain working all the time while reading this, i even had to reread some chapters to clarify things and make theories. i love a dark themed yuri definitely a 100/10 for me
