Both of them are boss and employee relationship.
Just you is more of a comedy as boss & me is more serious. ;-)

Both the dramas revolve around a genius who has a troubled past.

It deals with the same aspects of Love that is looked down upon. And how everyone no matter what they say , we all need someone in our lives to fill that loneliness. Its time for these two friends to re-discover there bonds. and along there way Discover who they are.

Both movies have similar theme about friendship/unrequited love about young people pretending to be in a relationship. Each are of a slow pace and have interesting and beautiful cinematography throughout. Their endings are very different, but I still recommended this because the storylines are both realistic with characters shouting with authenticity.

Focusing on crimes with big organizations that involves with drugs, human trafficking and selling organs. Both dramas are action-packed and dark with manipulative and manipulated characters. And characters who choose difficult ways to get their revenge...

Same storyline, great chemistry. It's really just a Chinese remake of Boys Over Flowers.

-Both "Daisuki' and "I wanna hug you" are about begim disabled woman ( Tsukasa is on wheelchair, Yuzu is mentally disabled)

-Both are about gettig pregrant by disabled woman, and become a mother

-Both heroines fighting with stereotypes, both of them wants to be independent

- Both heroines have a suppot from others

-Both "Daisuki" and "I wanna hug you" are from Japan

Both are set around the same era.
In both the characters are touring europe, so you get to see great views of europe.

Both involve hidding their royal identity.
In 'Khun Chai Pawornruj' it's the female, while in 'Rattanawadee' it's the male.

Both dramas have a similar feel, the way the OST is played in Descendant of the Sun, it brings out all your inner emotions, and it reminds me a lot of You Who Came from the Stars.

China is obsessed with both dramas to the point that nobody should be obsessed, so maybe you will get obsessed too^^

The plot sounds very similar.
-ill mother searches for father for her child.

Both dramas have hilarious and immature CEOs with a trustworthy and friend-like secretaries. Plot-wise, they are very different but both dramas are ridiculously hilarious and sweet.

the female lead is the same and both have kind of the same story line with family problems and skilled main leads in their deals.

Matsuzaka Tori is in it too!!!.
Japanese.
It's about thieves who steal to help the weak.
a woman who is manipulative because she knows the past.

It's also a crime drama that develops quite nicely and very unexpectly. There are many twists and surprises.

Its similar in the sense girl goes back in time and has useful knowledge from the future.
However in faith which is a full length drama the guy is a general and girl is a doc. Its more mature vibe and has some supernatural stuff.
In Splash Splash which is 2 ep. the guy is the king, and the girl is in high school, overall the drama is really cute.
