At these point im confused whether it was a manga or live action. So here it goes, the setting feels like it was from the countryside. The mc is female and keeps getting bullied. She ended up badly bruised so her parents went to school to complain, only for her father to be pushed down the stairs (spiked shoes) with his daughter bullies. The parents suggested she stay at home since the school would soon close permanently and graduation was only too months a way. So for a little while the female mc was happy. But back to school the bullies decided to find another target, the new target instead getting angry at the bullies for tormenting her, hates the mc instead, commits arson. And the female mcs father and mother dies while the sister is badly injured, thankfully the handsome ml(yet to be exposed as also yandere) saves her little sister. So yeah the mc knows all the truth and killed them all just honestly i remember all of it was fucked up and the ending ended in tragedy. I tried looking for it on google "bloody yandere female manga/live action" cant find it sjgsjavajvsvzh
So the ogML gets together with the heroine and throws away the villainess for "love" and ends up regretting it coz the heroine is dumb af and doesnt do her job as a queen. All the followers of the ogML want the villainess bacl because they all realize she is capable and has been taught her whole life to be a queen.
Or something similar with this kinda plot
