The Queen's Classroom (2013)

It's the Japanese and Original Version of it!

The Japanese version is actually the original version. It's good. I just preferred the Korean version. There's some differences with the storytelling. I recommend you watch both. One of the best dramas I've seen.

Drama series depicts the conflicts and struggles between a cold-hearted female teacher and her students over a one school year period.(asian wiki)

Both about bullying .
blackmail!

A teacher who cannot leave her students alone. The difference is that Misaki's ways to help her students are easily seen as helpful and caring while Queen's Classroom has more of a deeper and darker meaning.

The classroom as a space of power, violence and control. One of the few spaces where (poor) women can find power. Moon Dong-eun throughout the glory wants to bring everything back to the classroom, it is where so much begins.

Both Deal with Evil teachers that just rub you the wrong way. Both female leads have rich parents who try to make them what they want to be. They have to deal with the Evil Teacher picking on only them. Both leads and her friends help mend relationships between students. In addition, try to find out why their teacher is like that. If you like this drama the Queens classroom gives you the same amount of feels.
