Characters:
In Ji, a woman hurt by the concept of marriage decides to take revenge by joining a company New Marriage, which provides an ideal marriage service for people.
Jeong Won is a music producer and son of a wealthy man who gave him tons of trauma in his childhood.
Lee Seo Yeon is the b*tch and Jeong Won's ex-wife.
Yun Ji O, Lee Seo Yeon's husband and a nice party in the square-ship of all four characters.

What I like:
The premise of the plot is something new. Specifically the concept of how In Ji distances herself as identity from the marriage but does everything in the manual to provide an ideal marriage like holding hands for comfort.
All four characters, especially In Ji, are interesting on their own.
The movie-like production with specific silence-filled moments. The director is good.
How the plot shows marriage, dealing with toxic marriage/behaviour, the kind of down-hole a bad marriage can pull you into.

What I don't like:
It is somewhat predictable after 3 episodes. I could guess the next lines of the character.
