If you loved Xu Kai in either one of theses dramas, check out his fantastic acting in the other. Yanxi made him famous, but the legend also showcases his fantastic acting.

Wuxia. Strong Female leads, Dark and a little tragic. You watch the lead female grow and change her perspective on what is good and what is evil.

They both have slow plot yet interesting. The conflict also ups and downs slowly.

Based from the novel and has same genre: school life.

In a similar format to BLACKPINK Diaries, Jennie - 'Solo' Diary follows Jennie as she prepares and makes her solo debut.

Both Wuxia dramas have strong female leads who are funny and very lovable. You will be completely routing for these couples from beginning to end.

a recommendation isn't just about similarities, though I feel like both drama share the same sense of humor, it's funny but not overboard.. both also have 2 strong female leads and a "bad" lead that becomes a "hero" against their will

? Both Jin Mi and Hae Soo, the female protagonists, underwent a drastic character development from a silly girl to a matured woman. They serve the same vibe. Trust me and watch till the end for they are not same as they were in the first episode.
? There are parts where Xu Feng reminded me of Wang So especially when they look hot and brooding in all black ensemble. Xu Feng also became an emperor at one point. Unfortunately, unlike him Wang So failed to get the girl. (ANNYEONG PDNIMS, WE STILL NEED THAT MOON LOVERS SEASON 2 THOUGH.)
? Both OTPs showed a love that consumes you. You can't help but swoon and root for them. But, Jin Mi and Xu Feng's pairing triumphed above their circumstances which gave as a happy ending.
? Both Run Yu and Wang Wook, the brothers of the male protagonists, vied for the female leads' hearts. Their ambition for the throne also got in their heads making them the antagonists.

Both are about an alien who was left behind a long, long time ago on Earth. In My Classmate from Far Far Away, this alien is the female lead while in You Who Came from the Stars it's the male lead. The setting is very different, with YWCFTS being about the adult world while MYCFFFA primarily focuses on the student life aspect and has an overall more youthful vibe. Both equally amazing dramas!

Very intelligent Male and female leads. Both involve a smart strategising and political intrigue. Underlying themes of power dynamics and those in positions of power

a strong independent woman who knows very well fight that has nothing to envy men. Indeed sword shield arrow nothing has any secret for this one
  if you are looking for a woman with a strong character, this is what you need

an independent strong woman who knows what she wants that does not depend on man or anyone
who knows how to fight when it takes
go to war when it takes
and do nothing
  a woman who loves justice with honor and courage

It's almost the same concept except the donation part. They're all Star studded personalities and the beautiful village in Spain just makes it daebak!
These two shows are a definite hit to anyone who's a fan of even one person from the cast!

Female lead suddenly ends up as a secretary to a cold and socially awkward boss. Hate-love relationship. Jugglers has a bit more slower storyline.

They both have similar plots, with ghost seeing main characters, there is also a friendship which blooms in both of these stories.

Enduring love, sweet and great chemistry between leads. I thoroughly enjoy the story and pace of the drama.
