Recommendations

Both are supernatural dramas with vampire/vampire-like creatures. The protagonist in both dramas transforms into a monster after a traumatic experience. They both also refuse to turn completely into a monster and stay partly human.

A sassy rich lead moves to the country side and falls in love with a friendly, poor person. That person makes the lead change themselves and grow. Both dramas show the rural life and the people living there act like one big family. The shows show the beauty of a simple life.

Both dramas are about a princess who, due to circumstances, have to grow up outside the palace. For sometime in her life, she doesn’t know she’s a princess. She eventually returned to her kingdom and was a very good asset in helping/saving her people. Princess Deokman in Queen Seon Deok uses her wits, Princess Pyeonggang also does it plus she also fights some battles for her people.

> Both are well-made romance historical melodramas made 10 years apart
> Has a strong female lead that saves her male lead a couple of times
> Amazing performances from both leads to the supporting casts, and even a senior actor with a prominent role (Suyang in Princess Man and King Yeongjo in Red Sleeve)
> There are a lot of other historical romance melodramas (you can see from the other recommendations here), but these two dramas are both well made, received high ratings, and great reviews in Korea and abroad. Princess Man won best director and was nominated for other awards for Baeksang years ago, there’s a high chance the same will happen for Red Sleeve.
> Both female leads were called historical drama queens after their respective dramas aired
> The leads in both dramas received top excellence awards and best couple awards in their dramas' respective stations at the year end awards for their performances.

FM is crazy about ML
ML acts like he doesn't like her back
ML is smarter than her
SML is athletic and popular

both are school dramas that follow their friendships and are low stakes

these dramas both have similar themes to each other
trauma, family and friendship to name the main points
both balance the heaviness of the subject matter with breaks of light-heartedness (more so in IOTNBO) and humour.

Similar vibes. Both romances are between a prince and someone who works in the palace so its a similar dynamic there and comes with similar conflicts.

It's a story between clans just like in noble aspirations and the clans are completely opposite of each other...also due to past Life feuds and grievances the, ml and fl fall in love with each other in their 9th reincarnation . This also a very interesting drama to watch ...i especially like the ml as the efforts he put are really heart touching... although they get many misunderstandings in the way. U will like the chemistry of both the supporting couple as well as the lead couple ..MUST WATCH DRAMA!!

Both are sports drams.
This is not out yet but the title and synopsis just remind me of run on.
Both have interesting casts

Life of a palace maid getting loved by the prince/king.
Teaches a lot about Joseon's palace life
Romantic Sageuk.
FUN FACT: King in Dong Yi (played by Ji Jin Hee) is the father of the King in Red Sleeve (played by Lee Duk Hwa) i.e. great grandfather of Yi San (played by Lee Jun Ho). All three loved a palace maid.
Red Sleeve is a melodrama, whereas Dong Yi is more... eventful and happier perhaps?

both about two people living in a same body and the bromance is uncanny
both the male leads are self centred and think only about themselves

Both have general that fall in love with a smart FL. The FL is good with scheme and strategies. The FL also have few identities.

In both films, we follow two lawyers that are struggling to climb the ranks. Both lawyers are practical and is shown both in their work and personal lives. We also see the complexity of their character and begs the question will you be able to do what is right, even with the implications of it? Is humanity still alive?
