It felt like being gaslit by the show. The writers don't think much about women, rather they think of them in terms of men.
!!SPOILER ALERT!!
Reasons why those 3 wives were cheated on according to the writers:
1. DJ host (Hye Rung): She doesn't cook, she doesn't do chores, she's too willful and has a temper, she puts her career first, and she doesn't want children.
2. Writer (Si Eun): She's too much of a homemaker, will support her husband financially but is stuck to one routine, smells like medicine and looks like an old woman, and doesn't like sex.
3. Producer (Pi Young): This woman is too self-sufficient. Quite literally too perfect. She's beauty and brains and a good mother.
Reasons why those 3 women are the husbands' other women according to the writers:
1. Divorcee (Ha Ryeon): She cooked & cared for her ex-husband like the picture-perfect subservient wife she was and still got dumped due to her infertility. Surprise! She got preggers by the very man who was wanting children of his own. (She died shortly after giving birth, her role was quite literally to give this man a child)
2. Pianist (Ga Bin): She's adventurous, spontaneous, and cultured: the perfect woman for an art and theatre professor. And oh, she will consent to sex and needs a man to help around the house.
3. Small-time actress (A Mi): She's vulnerable, naive, and looking for an older brother to lean on in an unfamiliar land. (this case grossed me out the most, and the fact that Yusin is aware of that and still used it to justify their affair to his wife's face no less.)
All the male love interests, even the new ones in S3 (Seo Ban and his brother), have told the women in different variations, that men are wired differently and is more prone to cheating, so it's up to women to find peace and change their views on marriage and dating accordingly. The views being cheating is not acceptable. Yes, just the one.
The show reiterates more than once from S1-S3: It's not their fault, all men are going to cheat at least once in their life so be ready to forgive and forget and make friends with your husband's mistress. Be ready to be the bigger woman and accept that your flaw led your husband to look at another woman. Be thankful that your cheating husband or partner still goes home to your family after spending the day with their mistress.
At several points in the show, i had thought (had hoped) it was satire or a clever disguise to a satisfying end. The writers are serious. They're committed to their lazy and terrible writing. The burgeoning antagonist of the show is Hye Rung: the least ideal woman of the three. Makes me wonder if they were writing from experience as cheaters, mistresses, and gaslighting husbands, or just boomers.
I heard it's schedule conflicts but the actors who left S3 probably recognised a sinking ship and jumped. Can't blame them.
