Love this drama and surprised there's not much discussion...
I am surprised they showed us "all" the villains, at least some:
1. the male villain friend/ex - maybe child of a sidepiece holding grudge? Thought about *maybe* haein's "dead" brother then it gets a little incesty if he's trying to woo her...
2. The matchmaker - why is she with the family? It is kind of weird unless she's doubling as a maid/secretary?
3. The stepmom - super sus with the shaman and now the food stuff. Maybe male villain's "mom"?
I do hate MC being materialistic though and seems weird going from worrying about divorce and facing retribution to letting her die and collect $$$. I know it has to be there for there to be drama..
Do feel the ending will be bittersweet and he will have to take care of her or something. I mean tumors don't just disappear? She could've been poisoned too i suppose but even then it would take a lot to make her all better.
