3 Nen A Gumi: Ima kara Mina-san wa, Hitojichi Desu (2019)

Dramas where the parental figure is trying to save and guide the newer generation even when they themselves are falling apart. 3 nen a gumi is more radical while Shizumanai Hone is nuanced. Both have their own merits. Beautiful and heart wrenching stories.

In both the dramas the teachers are the villains ,
in 3nen A gumi hiragi is more of an anti hero, but in nightmare teacher uhm ki joon is the villain.
3 nen is practical but nightmare teacher is supernatural.
but in both the series students are tormented by their teachers, "who tried to teach a lesson "

This was also about a teacher teaching their class a lesson. The teacher put his students through a whole lot of drama. But in the end, he probably wasn't as bad as the teacher in Lesson of the Evil, since he was trying to teach students an important lesson that wasn't evil.
