Recommandations

Angry Mom is a drama and She's on Duty is a movie, but they both have driven female leads who go undercover as a high school student.

Same fantasy type elements
Male peruses female
Comedy mixed in
Both have the same feel

Koran odyssey is more action packed and intense and love knot is a bit more subdued but still great.

They are both Japanese dramas centered around independent or underground idols and the idol industry.

Similar themes. Female leads saves the world in the end for revenge. If you want to watch a drama with a female lead who isn't so naive, Princess Agents is recommended. Though both endings were not satisfying, but at least Princess Agents plot had more development.
Warning: That drama is also as twisted and graphic as this one.

Similar: Friendship, Business, Romance, Drama, Family, Melodrama.

Great chemistry in both.
Leads are superb.
Both are a bit lengthy.

In both movies, the basic plot remains the same. of two friends, one feels something more for the other and try to add more to their relationship

- Cold older female lead who is focused on her work and career and doesn’t believe in love or marriage.

- Warm younger male lead who still believes in love and marriage

I am sure that if you liked While you were sleeping you will love Extraordinary you.
Both have a love triangle in which the woman discovers first somthing fantastic that later she shares with the men: In While you were sleeping the demale lead can see the future and later the male leads too and in Extraordinary you the female discovers that she is a Manga character and later the male lead also thanks to her and also in both dramas the three main characters look for solutions to the problem and try tu change their fate.

I'am not good at explaining myself but I swear that you will not regret watching the drama.

A character comes « back to life » and lives near their loved one without him/her knowing it is actually his/her loved one (does it make sense?)

Although the subbing for flying colours is undeniably atrocious, they're very similar in that "persevere and you'll do your best" trope - not to say it's a bad thing! They're both rewarding and absolutely inspirational in that sense. Both feel good, x2000% romance in hajimete koi wo shita, and more feelsy (dare I say, relatable) for flying colours.

i found this dramas very similar although graceful family was quite better. they are both about very rich families, conspiracies, being untouchable, cult like groups, daughter in the family exiled or treated unfairly, daughter meeting a helper/guy that becomes a support system. AND most of all the villans, both dramas have the kind of villan you hate to love or love to hate. they were very good at being evil but somehow they got my sympathy. in both dramas the villlan had an unexplainable fondness with the male lead. graceful family is better because the leads have better chemistry and there was no forced/cringe romance like in the k2.

1) Both have a female protagonist whose soul leaves her body and has a 2nd chance at life by a reaper.
2) Both female leads discover secrets they didn't realize at the time of their deaths
3) Both show the horrid side of human nature that is revealed when the female protagonist is seeing it from a different perspective.

Even though the two dramas are very different, I think, people who love the Untamed will also like the Warrior Baek Dong Soo (the focus of the drama is on the relationship between two friends in Warrior Baek Dong Soo).

The plot seems similar. A special ops force/army man is working together with a doctor at a place amidst calamity/war .

They are both doing live streams in a haunted building. Disappearance has only one lead, but he's really interesting to watch. It also has a twist in it.
