Both include a teacher different from the others, a complex line of students and a hierarchy in the classroom is heavily implied

School 2013 is more student-focused in the main characters are two students with a complicated past friendship.

Both dramas have pretty much the same motive: to grow and nurture students into becoming adults. School 2013 is more heavy in terms of circumstances and conditions, but it's a must watch.

Both have:

- Teacher lectures and tries to change students
- Evil bullies with little self-awareness
- Bullying
- Teacher with ulterior motives to becoming a teacher

Both have:

- Teacher aiming to fix the classroom and dissolve hierarchy
- Growth in students and teachers
- Suspense
- 3 Nen a Gumi is more serious but definitely has a lot of the themes of Billion x School

Very, very similar. The main lead is a twin brother who takes care of his sister and has a difficult relationship with his father, and his mother remarried rich and all that jazz.

Anyway, it has the youthful, sincere, nostalgic feelings this drama does. It's got some good bromance as well, but mainly focused on the brother and sister, but these two shows have the same family and friend dynamics with a quirky, funny, yet annoying male lead lol.

Japanese action packed film. Full of fighting and conflict, it's an amazing movie franchise with multiple characters that all want to just protect who they love.

Based in the Joseon era of Korea, it's historical and full of action and fighting just like this movie.

It's dark, centered around crime and very, very sad. It also has a huge plot twist and a star-studded cast. Really recommend.
