Happiness (2021)

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.

Though the genres are quite different there are some similarities.
> Both feature Park HyungSik
> ML falls in love first
> Both FLs are strong ( in SWDBS she is extraordinarily strong)
> While SWDBS is RomCom, happiness only has slight romance but both leads have amazing chemistry.
> Both ML and FL protect each other. (In SWDBS, she is actually his bodyguard)

both has strong female lead
both has romantic affection, neither hidden nor openly
happy ending
unexpected twist
exciting to watch, not a single second was boring

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.

In a post-COVID world, long-time friends, detective Jung Yi-Hyun, and Special Operations Unit officer Yoon Sae-Bom, strike a deal to secure an apartment in a newly-constructed high-rise building, just as an infectious disease breaks out.
This thriller drama sees an apocalyptic world where virus has created a havoc and residents of an apartment are surviving for their life. Happiness had a decent story with a very good production and overall visuals. The soundtrack though, was the best part in the entire drama.

If you like Exit for the intense scenes, the quality, the drama, and the comedy, then you will surely enjoy Happiness as it has all those factors. The FL, Yoon Sae-Bom, is a strong FL, she is decisive, determined, and does not easily get rattled. The ML, Jung Yi-Hyun, he is smart and honest, protective, and quick on his feet. They are a power couple, so if your more into EXIT for the comedy, you may not enjoy Happiness AS MUCH, but still, give it a watch, there are a bunch of comedy scenes you can come to enjoy.

it's the same survival from either zombie or monster in the same house . quarantining and surviving. and an suspensive survival drama

Similar aspects /elements between these two dramas. Bulgasal so far has less gore and has a fantasy element to it but both a have romantic relationship and I think people who liked Happiness might enjoy this one too!

I have yet to watch the drama (Gyeongseong Creature), since it hasn't been released yet, but I already see a few similarities such as:
Genres: Action, Thriller, and Sci-Fi
Cast: Great, Fairly Well-Known
Concept: Humans and Monsters/Creatures
Involves: Investigations

They both are about a virus/ flu spread . I feel like everyone who likes these kind of shows would like both.

Both have similar vibes as they are stuck in one apartment complex, and the outside is dangerous. Also, both are survival show/movie.
