The female leads for both dramas are alike in terms with their disposition, competence in their career, hidden emotional vulnerability, and the fact that they were betrayed by the people that matters to them.

I would recommend V.I.P if you want a less vengeful, quite insidious attacks of betrayal. As for Guilty, you are in for a fast-paced ride with big revelations that may surprise you.

If you want to see more of Kim Hee Ae drinking red wine and being cheated on, you should watch the other.

Both are also adaptations. The World of the Married is adapted from the UK drama, Doctor Foster while the movie, The Vanished is an adaptation of a Spanish film, The Body.

If you have watched Doctor Foster (the TV series where this drama was adapted from), you wouldn't have made a connection, but this Korean adaptation and SKY Castle both have themes of greed for connections to social elite.

Both also have high ratings in South Korea, and their mystery genre may have been also a big factor contributing into it.

To be honest I got confused with the title with these series. Both have the same dark theme and body switching trope, but they have different storyline.

Both have:
- themes of the political side of the corporate world
- lead characters struggling from the affair of their spouses
- binge-worthy episodes

Both revolved on the revenge of the powerful female leads fighting their claim for their family and position in the world of the rich.

The friendship of the main characters in TBMTQYJ reminds me of the main characters of the BM. Although the former's relationship wasn't as deep as the one in BM, all the characters struggle with living life as independent adults.
