Is My Royal Nemesis Based on a True Story?

The drama is fiction. The woman behind it is not.

This year, two fantasy romance dramas set in the Joseon dynasty aired in Korea around the same time.

One drew fierce backlash from Korean viewers over historical inaccuracies. The other started quietly, hit double-digit ratings by episode six, and became the first SBS Friday-Saturday drama in history to reach number one on Netflix’s non-English TOP 10. The difference, if there was one: the second had comedy.

The first was Perfect Crown. The second is My Royal Nemesis.

But to watch this drama properly, you need to know something first. Gang Dan-sim, the protagonist, is a fictional character. Every element of her story, however — court concubine, royal poison, political sacrifice, reincarnation in the present — was taken from a real woman. The most dramatic life in five hundred years of Joseon history. Jang Hee-bin.

My Royal Nemesis — Should You Watch It? Yes.

Agree to the admittedly ridiculous premise — a Joseon-era villainess possessing the body of a modern-day struggling actress — and something unexpected opens up. A genuinely new world, exactly as the Korean title promises.

Im Ji-yeon’s performance as Gang Dan-sim is funnier and more natural than anyone anticipated. The discovery that this actress can do comedy — and do it this well — is its own pleasure. International viewers are already reacting on YouTube.

Where Perfect Crown put romance at the center, My Royal Nemesis puts comedy first. Romance follows.

Gang Dan-sim = Jang Hee-bin — The Woman Who Created the Biggest Scandal in Joseon History

Gang Dan-sim is fiction. But her entire setup — concubine, royal poison, political scapegoat, reincarnation — was drawn from the real Jang Hee-bin (born Jang Ok-jeong, 1659–1701).

Jang Hee-bin was the only person in five hundred years of Joseon history to rise from non-aristocratic origins to become queen consort. She started at the bottom. She reached the top. And then she was ordered to drink poison. By the king.

The Woman the Royal Annals Bothered to Describe

The Joseon Royal Annals are an official historical record. They document politics, policy, and governance. They do not, as a rule, describe how women look.

And yet, in an entry from the twelfth year of King Sukjong’s reign (1686), Jang Hee-bin’s beauty is directly mentioned — written by the very political faction that opposed her. Her enemies put her appearance on the record.

It is one of the rarest instances in the entire Annals. And it echoed for centuries.

Just as Britain and America keep returning to Henry VIII — remaking his story for every generation — Korea has kept returning to Jang Hee-bin. And an unspoken rule developed: whoever plays her must be the most beautiful actress of that era. The role passed from generation to generation.

In 2026, it went to Im Ji-yeon. In a form no one expected.

Im Ji-yeon — Yeon-jin Is Laughing

International viewers know Im Ji-yeon for one role above all others. Yeon-jin in The Glory — one of the most chilling villains in recent Korean drama history.

That same actress is now playing a character who panics in a convenience store, scolds a part-time worker in archaic Joseon court language, and gets constantly outmaneuvered by a cold-blooded heir. International reaction has been uniform: “Yeon-jin is doing what?”

That disorientation is part of the drama’s appeal.

What Possession Means in Korean Drama

In Western drama, possession is horror.

In Korea, it’s something else. The idea of someone who died with unresolved injustice returning to the present connects directly to “han” (한) — one of the defining concepts of Korean emotional culture. Unresolved grief, unjust death, the desire to settle what was left unfinished.

Gang Dan-sim drank poison and woke up in 2026. For Korean viewers, that’s not just a fantasy setup. It carries emotional weight.

There’s a scene in the drama where Gang Dan-sim watches a historical television series about Jang Hee-bin — without realizing it’s her own story. A woman who died unjustly, watching how history chose to remember her, without knowing that’s what she’s seeing. It’s played for comedy. It lands as something more.

This Drama Finally Got the King Right

This is something even many Koreans don’t fully know.

In every previous Jang Hee-bin drama, her husband the king has been portrayed as essentially good — a ruler who gets drawn in by Jang Hee-bin but ultimately makes wise decisions. That image has been repeated for decades.

The historical reality was different. He was volatile and unpredictable, and executed officials who crossed him with disturbing ease. The sequence of events in which he elevated Jang Hee-bin to queen, then stripped her of that title, then had her poisoned — this was not the behavior of a wise monarch. It was the behavior of a cruel and erratic man with absolute power.

In My Royal Nemesis, the king figure — Choe Moon-do — is the villain. The grand prince, Cha Se-gye, is the good one. The drama never explicitly names Sukjong. But it finally gave that king the portrayal history actually warranted.

What Perfect Crown Got Wrong — and What This Drama Got Right

Perfect Crown built its story within the actual framework of Joseon history — and paid the price when Korean viewers found the historical details wanting. Borrow history, and history holds you accountable.

My Royal Nemesis set its characters as complete fiction from the start. Gang Dan-sim is not Jang Hee-bin. She is a character inspired by Jang Hee-bin. That single decision made historical controversy impossible. And yet the historical context — the real dynamics of Joseon court politics, the actual character of that king — runs through every episode.

That’s a smart piece of writing.
