The whole setup and story are somewhat cliche, to be honest, but this series has a lot of twists and turns and plots that would always leave you wanting for more. It really exposes the reality of a failing/failed marriage. The actors were really delivering the emotions which add up to the story and the whole vibe of the series, not to mention the antagonists that would make you want to hurt the screen you're using. Kim Hee-ae (Dr. Ji) was really outstanding by showing us her range. Lastly, I loved that there were many parts where the story educates and addresses issues on sexism and mental health.
