Whilst watching i felt like Monster(2023) reminded me a lot of Ningen Shikkaku(1994) and shared many similar elements, for instance:

- Multiple perspectives
- School Bullying
- Strange/psychotic teachers
- Dysfunctional families
- Bully befriending victim
- Parents trying to seek justice for their children
- LGBTQ relationship between male students
- Brutal and depressing

Eternal Yesterday and Happy Of The End are completely different in terms of plot, but both carry a strong sense of misery throughout its runtime.

I saw many people saying how the lead characters in Love For Love's Sake are similar/remind them of the ones in Weak Hero Class 1, just in a different universe.
