Happiness

-Both feature Park Hyung-sik.
-Both have long time best friends where one has feelings for the other.
-Both the leads have to live together
-Leads share loads of chemistry

*in both drama main leads are cops
* both female leads are badass and stubborn
* the chemistry is really the same(they care about each other a lot)
*both male leads are sweet and lovely
(maybe the genres aren't alike but after watching happiness I found catch the ghost satisfying, I've been looking for a drama like happiness and catch the ghost was my gem)

Both the main genre of zombies, layered in story of humanity and conspirocies between characters. The story behind the infectation is well-explained and thought-out.

The vibe of both dramas is very very similar, you get the same feel as you watch them, plus they both have that mystery vibe to them that makes you want to keep watching, and sad events that are also similar. They just complement each other if you want to feel the same as you did in one of them.

Both are about people trapped inside a building during a zombie outbreak with the owners of the building more concerned about their money and status than the people's lives and the lead couple working together to survive.

A fresh and unique spin on zombies. Zombies still have consciousness and can speak after being infected.

parallel word is a fantasy action drama it is really something completely different from happiness not even similar but I found the relationship between the leads similar, they are always there for each other and protect each other the chemistry between the leads is great and I have long searched for a drama that is similar to the relationship between the leads from happiness and just wanted to suggest parallel word for people who also loved the happiness couple.and the female lead is such a bad ass i love her personality she is such a cool character.

Though the genres are quite different there are some similarities.

both of these korean dramas , All of us are dead season 1 and 2 and Happiness have similar plots. The main concern is the zombie apocalyse which happend in both of these korea dramas. that's why i think watchers would like to watch Happiness if they liked all of us are dead season 1 and 2.

First of all both of the drama gives the same vibe. Like both of it are about fatal diseases. Fight against the disease. One of them have to save the other one type of things. In there both the towns are under this disease. And they together try to save the town while saving themselves

You have the unspoken romantic vibes between the leads that a develop/have similar vibes to a slow burning romance and a show where I personally got similar vibes from (romance wise) is happiness, it’s a really cute slow burning romance, although in this serie it is spoken about even though it’s not the main theme.

Both have some kind of genetic mutation kind of feel to them and both feature the same Female Lead with a few differences.

IT IS ONE OF THE DRAMAS THAT I REALLY ENJOYED WATCHING TODAY IT IS MY SECOND TIME START WATCHING DARK WHOLE AND WHEN I FIRST FINISHED HAPPINESS I HAD THE SAME FEELING THAT I HAD WHEN I FIRST FINISHED DARK HOLE THAT I WILL BE WAITING FOR THE DAY THAT I'M GOOING TO WATCH IT AGING.

It follows the trouble-filled daily life of a mysterious and strikingly beautiful vampire novelist who assists the police in criminal investigations, and a rookie editor who finds himself at the mercy of a non-human existence.

Zen Misaki is a wildly popular bestselling author whose true identity is, unexpectedly, that of a vampire. Using supernatural abilities unique to his inhuman nature, such as nensha (the power to read a person’s memories from their blood), mind reading, and hypnosis, along with his sharp deductive skills, Misaki stylishly solves difficult cases that have left the police at a dead end.

Having long since abandoned his life as a human, Misaki begins the story having lost his sense of purpose, lacking the passion to write new novels and harboring a cynical, world-weary outlook. However, through his interactions with a young editor and an up-and-coming detective, and by solving case after case, he gradually rediscovers his capacity for love, friendship, and the very emotions that make him human.
