I've not watched Misty, so I'll go with the vibe I get : educated mature woman, maybe divorcee, who's not very nice?
The Good Wife A betrayed wife who needs to build back her life and carreer
I Have a Lover A hard, cold wife who's willing to do anything to get her husband back, Then makjang ensues. It's a makjang but very well done, really.
Cheongdamdong Alice A wannabe gold digger who will do anything to marry rich.
Encounter She's rich and divorced.
I Hear Your Voice She's kinda cold and money hungry too.
