I'm actually quite surprised the rating is this low - in terms of plot, writing & the concepts this drama touches, I feel like not so many are on its level.
Definitely a well-built revenge story that never feels pointless or stupid as it often happens with other dramas inside this subgenre.
The casting was on point. A group of amazing actresses that were able to handle this story without the big presence of a male star, still quite rare in the drama world.
Definitely would recommend to people that aren't used to watching Asian TV / people looking for a drama that feels like something you'd watch on American TV.
9/10.
