Chastity High

Similar high school plot with a poor kid in rich school surrounded rich kids
But renai battle royale is everything that hierarchy should have been .A fast paced ,engaging drama with a unique plot .
Where Netflix Korea failed with Hierarchy as a high school romance/mystery thriller ,the Japanese Netflix shows them how to do it properly.

If you like a school drama wherein male-female relationships are prohibited, you will like the other drama. It won't be a repetition of the plot at all since the genre is really far from each other. RNS is comedy while RBR is mystery and a lot more serious. Also, Honda Kyoya is in both dramas!

the main premise isn’t similar, but the two dramas involve prestigious high schools in which poorer female leads are able to attend. in both, dark events occur but in bxtch x rich they are darker.

Both Jdramas, both centre around school, both have unique schools where things only happen there and no where else, both involve a bit of mystery, suspense and high stakes. Chastity high is more uplifting though, Mr hiiragis homeroom is darker.

School rules being unreasonable for students. Resistance. Jdrama. Good looking guys. Hmmm why I’m becoming bad at this? Forgive me for my brain is not working. I’ve only had 2 hours of sleep. Why did I binge watch Chastity High when I should be sleeping?! Because I can’t fckin sleep I hate myself

as soon as I read the jdrama synopsis it reminded me of extracurricular except the roles are flipped.

In the Kdrama the ML is poor and takes advantage of classmates to earn money (there is a lot of context behind this). I believe he doesn't have a mother and his father is up to no good either. And the FML is rich, she has everything she could think of apart from freedom. One day she finds out what the ML is up to and takes part in it for fun and to run away from her family.

According to the jdrama synopsis, the FML is poor and has a single mother. To earn money she takes advantage of classmates situation. ML on the other hand is rich but has no freedom. One day ML finds out about what FML is doing and takes part to make money and run away.

Both dramas are about suppressed students by overwhelmingly strict rules by the school.
Both student bodies are getting rebellious and trying to change the system.
The vibe is similar, even if one of them is more centered around BL only, while the other shows all kinds of love and relationships.
