I do not understand the high ratings. This so-called romance drama included no romance whatsoever. The ML was a depraved, misogynistic, narcissistic, spoiled, entitled, boy masquerading as an adult. And incapable of taking responsibility for his actions.
The FL father was a sadistic, abusive, greedy, guttersnipe that needed to be disappeared.
The FL Aunt had Stockholms syndrome.
All of the men were unfaithful in one way or the other. The Main daughter-in-law was complicit in treating the other women of the house as Stepford wives while having an affair with her deceased husband's brother.
The Grandfather was living in the dark ages but meant well.
