Everything was planned out perfectly! Dong-Eun's long planned revenge was satisfying to watch as her bullies began to attack one another! Wish that the punishment was more severe but still glad that in the end dong-eun got back at every single person who did her wrong in the past, & ended up begin with the doctor at the end! Glad that Yeon-Jin is suffering the way that she made dong-eun suffer & that she got one no by her side behind bars! Its Overall the best k-series i came across on Netflix!
