This fits the bill if you are a connoisseur of Makjang daily dramas. All the necessary tropes were at play.
A secret plot that cleanses the sins of the mother. Birth secret. Memory loss. Slapping, loads of slapping--actually a bit too much, but it was comical.
Dopey first husband and his greedy mother get hammered by karma.
Falling off cliffs, getting hit by cars, paralysis, secret recipes, stupid counterplots with women impersonating men... the list is endless.
My favorite character is Se Ra's mother. She was a true Makjang character, even after her death in prison.
Wonder what is next at this time slot?
(Please don't torture yourself thinking there are actual writers for this genre, what you have is a formula, a small apartment and lots of soju and ramen)
