The ending (SPOILER)
Very disappointed in the ending.
Here I how I would have ended it: To say Kim was vindictive is an understatement. I would have had a trial in which part of her defense was calling Seo Jin to the witness stand and playing excerpts of her conversations with Kim that implicate her or at least make her look really, really bad. Seo Jin’s family is in the courtroom. As this evidence comes out , Seo Jin is ashen and her family share in her shame. It is clear, no happy endings for the Kang family. Fade to black on Seo Jin’s shattered face.
