Like The Untamed also adapted from novel and features BL characters. Bromance is major plot line in the drama. Like Untamed also focuses on crime solving but both of them are on different level.

Both dramas have similar vibes; they are both about mystical elements (ghosts or dreamworlds) set in a modern-day world.
The female leads in both dramas are tough, powerful and strong while both the male leads are introduced to a new world of either seeing ghosts or entering dreams.
If you like Hotel del Luna then you will like Mystic Pop-Up Bar and vice versa.

Both dramas' story are set in Unified Silla Dynasty, both main character from both shows are played by the same lead actor and about the same premise, merchant, sea, war. And this show has reference Jang Bo Go the main character of emperor of the sea a few times in emperor Wang gun and also directed by the same director.

Male MC is married to a mentally unstable woman who has the same fate in both films. There is an age gap element in both, as well as a professor/student element. Papakatsu is more of a romance show though and Scarlet Innocence is honestly kind of fucked up

Obvious link : Similar themed movie with a spreading outbreak
The characters then have to survive this outbreak

-Both is about ghost
-Both have jealousy between the main lead
-Both storyline is main lead disliking each other at first.
Nonetheless, each of them have their own storyline and is both amazing!!1 :D

The story line is pretty similar, protecting the other one from ghosts and last episode is also about after life so really recommend it!

They are both dramas revolving a career-minded FL who finds peace in the quiet of rural Korea.
The stories are quite different, but both shows have the addition of a makjang revenge plot which is a bit detrimental. This is worse (in my opinion) in Eccentric! Chef Moon. My Husband Oh Jak Doo is a bit more consistent with its premise, but still there are some makjangish elements especially in the second half.

Both of them have Jung Hae In as the Main Lead. The Chemistry between the Leads are also So Good. Even though the story is different, the feeling that both if them give are similar. Both of them focuses more on the leads and not on Side stories.

The genre is almost the same but the story is quite different, nonetheless, Love O2O is really great :D

Both are based on the China dynasty period.
The difference is that, TSOMD is mainly a detective show where they solve case by case but eventually saving the emperor from rebellion. It focuses more on the thing that happen around the royal Palace.
As for nirvana in fire, they focus more on the things that happen in the royal Palace, and the main character is trying to help the Prince becoming the next emperor. You'll see the details about how the emperor works, their concubines and the way the Princes are trying to get their hand on the throne.
Both are equally nice, tho the goal is different.
