More than the story of one infidelity. Non-standard, and therefore extremely boring drama, a little comedy, a lot of detective / thriller.
So we have:
A writer who continually invents new ways of killing. And she doesn't just invent them. If it is the poison of a plant, it will grow it at home; if it is a chemical, it will buy it. The character is such that people are afraid to approach it, and they do it right. Very smart, but kind of blind when it comes to her husband. Or is it not?
Her husband, who cheats on her with everything that moves, but at the same time, firstly, the best husband of Korea, according to the media, and secondly, signed some interesting paper.
Her assistant, clearly overqualified for a simple assistant, and who definitely has his own goals and secrets.
Her publishers, who kind of beg her to write a new book, and then do seemingly strange things.
Her mysterious book, which seemed to be, but which is not. And her new book, which will be about what? Perhaps the murder of an unfaithful husband? Maybe.
And a bunch of characters, ambiguous and at first mysterious. And a lot of secrets and secrets. And believe me, you should watch this, because it's much more interesting than the banal "story of one infidelity."
