if you like food's, chef and cooking drama and love triangle in the mix.

Both tell a story about founding a kingdom. Moon Lovers is based on the beginning of the Goryeo dynasty while Six Flying dragons is based on the foundation of the Joseon dynasty.

Both dramas have a similar vibe to them, be it the plot or the acting. Both dramas will make you smile and cry a lot. The music & cinematography in both dramas is also superb.

Both movies tells the story between the King of Qin and his assassin. Hero is more artistic, where The Emperor and the assassin is nearer at the historical story

You will see a different Zhao Li ying here. There will be a lot of ZLY and ofcourse her amazing drama skills. Of all the ZLY dramas I've watched this one is my favorite next to Journey of Flower.

Say that You Love Me loosely follows the basic story of Itazura Na Kiss, however it's different too.

Elder brother revenging for younger sibling by kidnapping the nang'ek to deserted island. But only to find out that he revenging at the wrong person later.

Ok, these are clearly nothing alike. But after watching SHR, I wanted something with a questionably crazy male lead. Yoo Jung reminded me of Wang So because neither are the typical "jerks," but they are not really nice guys either and they both make me wonder if either is really sane lol. And they kind of treat the girl the same way.
And both have the same combination of romance with a bit of suspence and an open ending.

they give off the same vibe. the two main girls remind me of each other. the two main guys are jerks to the girl the majority of the drama.

Athena is a spin off from Iris. They are very similar with a different cast and a slightly different story. The action, suspense and romance are as amazing as in Iris.

both are based on crime-romance novels by ding mo. have the same feel.

they are both based on novels by the same author (ding mo). both crime/detective and romance series.

Both talks about someone forgetting about the memories they have with their friends.
In the movie "One Week Friends" it talks about a girl who can't remember the memories that she had with her friends, and in "Forget Me Not", it talks about a girl who everyone can't remember of the memories pass with her and who she is

Something about 1 Percent is a remake of 1% of anything. I think the earlier version is quite charming.

Seems like the same kind of premise. Guy and girl work together to solve crime, guy falls for girl slowly and girl is even slower, and the killer comes to ruin the moment.

These two dramas give off very similar vibes. They are both on the more serious side, plot-focused with an actual lesson to learn from.
Whenever I think of one, I automatically think of the other.

Jungle Fish 2 (which is not really related to Jungle Fish 1, so you can watch it by itself) is about a girl who has died, and her group of friends try to find out why. It reveals a lot of hidden secrets about the school they go to, and about how many flaws there are the school system.

White Christmas is also focused on a group of people who are working together to try to get out of a horrible situation (It's hard to explain without spoilers). The students in both of these dramas face different but similar problems, and have similar yet different back-stories of their own.

I highly recommend watching both of these!
