2022 is really the year for good crime/psychological shows. this one and through the darkness are both doing down as two of my favorite thrillers ever.
Actually there are not too much dramas about bullying. And also not many of them are even 8/10
many of the dramas that i've seen include some sort of bullying subplot (e.g. extracurricular, all of us are dead, true beauty, run on, etc), so it's definitely a popular topic amongst kdramas. and i wouldn't generalize because a lot of them are pretty damn good!
the last episode was a total cry fest but other than that i feel like the rest of the drama was pretty mediocre. even in chanyoung's death it was about mijo. would have replaced 50% of her and sunwoo's scenes with joohee and hyeonjun. 7.5/10 for me.
