all genres are the same. The ML is a badass and the FL is also a lawyer in both. The ML is involved with mafia/gangs in both soo yeah seems pretty similar!

It has similar concepts to afterlife and evil spirits
and if you want to see rom-com this is the best

Both historical dramas, highly recommend watching, it takes place after the Joseon dynasty during the Japan colonization so it kind feels like it is continuing the story from another point of view

-Both have strong female leads who are very competent in their careers
-Both deal with the aftermath of infidelity and getting revenge on a cheating partner, although She Would Never Know seems more focused on romance, where The World of the Married is more dark and focused on the revenge aspect
-Both involve possessive/obsessive male leads
-Both have workplace love interests

While the plot is different it is a relationship between two public figures. They also take place in the period of COVID.

Both female leads get a second chance at their teens. The question is will they be able to change what happened in the past?

Similar "time travelling" theme. Lead(s) travel in time and try prevent some events from happening in order to ease their regrerful hearts.

both are a simple love story/romcom, and very few misunderstandings involved, hardly any, great communication and trust between both couples. Both are soft and lighthearted.

The only thing that is similar is that both these dramas are about idols. So if you're wanting to watch more dramas (or webdramas) involvinhg idols, i recommended top management :)

Love and redemption is similar in female cast
The female cast has incredible strength. She doesn't remember anything from the past. She thinks she likes some guy, but she liked someone else entirely. These dramas are a powerful cup, but worth a look! Actually, when I watched this drama it was about 1 year, and I happened to watch "Love and redemption" last week, I thought it reminded me of something because female leadership is really great!
I recommend this drama

Both FL traveled back in time and met the younger version of their mothers. They later became best friends.

If you liked 'Walking at Night' aka the last segment of Persona then maybe youll also enjoy Come, Closer since they have the same director/screenwriter and both feature scenes in which the characters are going for a walk.
