Mine

Both dramas have a woman out to get her daughter back from her shady ex, and teaming up with women that were originally her enemy in order to do so. Additionally, they both just have a lot of morally gray/complicated female characters. Queen of Masks is darker than Mine, while Mine has a more polished veneer and perhaps a more optimistic outlook overall.

Makjang drama, cheating husbands and complicated family dynamics will feature in both.
