Weak Hero Class 2

Both of them offer intense storylines that delve into the complexities of youth, crime, and retribution.

-Both revolve around school bullying
-In both dramas, rather than a story, the MC is the plot. It's about them surviving and evolving.
-There is a lot of difference story-wise. The Glory is more about revenge, whereas Weak Hero is about eliminating the problem (bullying) itself. But emotionally, I think both dramas give the same feels
