Not a casting post, but a tale that this happens a lot in real life when actors play villains so well that the public hates them in real life. It has happened to many actors from Game of Thrones and even Harry Potter series. Here is an example:

It took Tom Wilson years to overcome playing Biff, the McFly family's nemesis, in BACK TO THE FUTURE. He recounted in a 2017 interview:
“And so the interchanges I would have [with fans] - of course, most of them were positive, and most people understand the movie, but there were plenty where the guys would want to put me in a headlock, or push me around a bit, or get into a little tussle with "that tough guy from Back to the Future, because he’s not that tough after all." Well, I’m not that tough after all, because I’m an actor; because it’s pretend!”

Gu Jun-pyo will always be looked up to as the standard to meet when it comes to Too Toxic For You™ 😂👍. And it turns out that after giving us her (in)famous work, the writer has produced something sensible like Move to Heaven (which I think I should watch). So she could write this drama within a drama as a thinly veiled dig at herself. It should be called Man-child Harassing Flowers. Cast our OG ML as the man-child (I don't care if he can "break the character", I just want to see the writer poke fun at what she created back then). I don't want it to be a romance either. That would beat the purpose of creating a satire around Too Toxic For You™. So bring in the other OG aka Kim Bum as the writer and make it a F2 bromance (I have more faith in Kim Bum's ability to both make and break a character). Do not spare any opportunity to point out what all was icky about the OG, bros! 👍

Writer: Yoon Sanghoon.

I have a feeling Lee Minho fits the main character.

Hmm.... I have three recommendations for actors to play the male lead of different age range:

Lee Jae Wook (his character from Extraordinary You) - 20s
Lee Min Ho (Gu Jun Pyo!) - 30s
Jang Seung Jo (his character in Chocolate) - 40s

The female lead is Seo Hyun Jin (the writer). This is her fourth drama production and people had high hopes for it because of her previous successful dramas but it's failing and she doesn't understand. Jokingly, open night when drunk, she confesses that the male lead is based on her ex-boyfriend and promises to forgive him if he faces her (the only problem, said ex is dead). Claiming she left a door open for him, she falls asleep on her work table and her tears work some magic on the script and the ML walks out!

So Ji Sub can play a crappy kdrama lead that visits the real world. I didnt check out Doctor Laywer but I may watch this.

Alternative actors can be: Hwang In Youp and Kim Woo Bin

FL writer can be Seo Hyun Jin, Jung So Min or Kim Ji Won

Two people come out of the drama "FAITH"

1. Lee Min Ho's Choi Young. He's not exactly problematic, but I'd love to see his character become the fish-out-of-water. But really, he's just along for the ride because I'm more interested in...

2. the cartoonish villain in Faith, KI CHUL played by Yu Oh Seong. He'd be so lost is today's world -- not only is he out of time, he'd be so surprised and frustrated because none of his magical powers work! And he has no one to scheme scheme-y things with!

As for the writer-nim, she's a cutely unkempt, forever flustered but super rich Park Bo Young. Who'll adopt our drama duo.

ML goes back to the drama world early in the story, but KI CHUL gets stuck and eventually forms a lovely father-daughter relationship with our FL, which is the main arc of the show.

Admittedly I haven’t watched so many k-dramas with different casts, so this may not come across as much inspired, but the ML could be well captured by *Ahn Bo-hyun*, in my opinion. As for the harangued drama writer, I put forward *Shin Se-kyung* - let’s get her out of the sageuks and into a comic relief role again!

I'd like to see a really tall and dashing actor playing a red flag character. Because we know by now that in the real world sometimes it's the most likable and popular guy that ends up being an abuser and nightmare. Let's play the devil's advocate and cast "the good guy" Na In Woo. While watching Marry My Husband, the entire time in the back of my head I was thinking to myself, how funny it is that oftentimes it's the guy who looks like the lead (re: tall, handsome, nice) is the one that becomes the troubled husband later on. Sometimes there are red flags and sometimes there aren't enough to see because they're so well hidden.

My choices for the ML (in no particular order):
Kim Bum (based on his performance in Tale of the Nine-tailed)
Lee Dong-wook (again Tale of the nine-tailed)
Wi Ha-joon (who was a riot in Bad and Crazy)
So Ji-sub (based on his performance in Master's Sun)
Ahn Bo-hyun (based on his performance in Military Prosecutor)

For the writer if it's a woman:
Han Ji-min (who has a killer death glare ala Familiar Wife and plays the exhausted, overworked role very well)

For the writer if it's a man:
I'd like to see a reunion between Kim Bum and Lee Dong-wook with Lee Dong-wook playing the drama character or Lee Dong-wook and Wi Ha-joon with Wi Ha-joon playing the drama character.

“Goo Jun Pyo, first order of things: Go get that hair of yours tamed. You’re not a drama character anymore nor a manhwa character anymore. With that hair and your stink attitude, you’re going to get your butt whipped. I’m just trying to look out for you, Mr. Chaebol *coughSpoiledBratcough* “

Up-and-coming idol-turned-actress Riwon plays a plucky Kdrama writer—full of determination but lacking a single original idea—who miraculously finds a studio willing to produce her show, called A Bad Day to Be a Cat. Not surprisingly, the show has been steadily losing audience share. Cancellation looms on the horizon.

In the drama-within-the-drama, Jang Na-Ra plays a Joseon princess who is now living her 19th reincarnation as an aloof chaebol daughter. For centuries, she has been searching for her beloved, a handsome nobleman (Jang Hyuk) who gave up his soul to save her from an evil enchantress. His sacrifice doomed him to an eternal existence as a tabby cat, reverting to human form only on the night of a full moon. The spell can only be broken by the princess’ kiss. Unfortunately, any living creature she kisses other than her beloved will turn into a spicy chicken nugget. To avoid inadvertent catastrophe, chaebol princess keeps everyone at arm’s length, earning her a reputation for being cold and unapproachable.

Just before dawn on the night of a full moon, she catches a brief glimpse of her beloved in human form. But with the first ray of sunlight, he turns back into a cat and scampers off. Heartbroken, the princess takes to roaming the streets and alleyways of Seoul each night, snatching up and kissing every stray cat that bears even a passing resemblance to her lost love. A hunt then begins for the heinous night prowler who has been kidnapping neighborhood cats and leaving behind a single chicken nugget in a pool of sauce.

On patrol one evening, the police spot someone suspicious exiting an alley, trailed by the unmistakable odor of dakgangjeong. Finding the telltale nugget, they chase our heroine through a maze of streets, until they are certain they’ve trapped the cat burglar in a dead-end alleyway. When they arrive, though, there’s no one there.

Realizing that she trapped her fictional protagonist in a seemingly impossible situation, writer-nim hastily adds to the script a secret alleyway portal that disappears as soon as chaebol princess escapes through it. She emerges in the writer’s bedroom. Needless to say, she's furious over her royal character being turned into a ridiculous chicken nugget sorceress and reviled cat snatcher. Worst of all, if this lame drama is canceled, the princess and her eternal love will never get their happy ending.

Back in Joseon days, the princess was the acclaimed but anonymous author of a series of racy romance novels. She knows a thing or two about writing a good story, though she hasn’t kept up with literary developments since the 16th century. She insists on taking over authorship of the drama, but her ideas don’t easily translate into the 21st-century. (The spot by the tree swing where the princess and her lover used to meet in secret is now occupied by a Quiznos, and there aren’t any eunuchs or palace ladies around to convey secret messages.) When she proposes telling the...

I dont know why the writer should.
I would just kill off the character except he cannot die bc he is a character
it could be a crazy action adventure and he could gain fame as the Immortal Jerk who seems to survive miraculously even through the freakiest accidents.
Since Siwon only got to die once in Deaths´ game he could play the main character
