My Royal Nemesis Stars: Who Lim Ji-yeon and Heo Nam-jun Really Are

Netflix's #1 non-English show stars two actors who seem cold on screen — their off-camera personalities, revealed in a viral YouTube interview, tell a different story.

The Villain from The Glory Has Left the Building

If you know Lim Ji-yeon from Netflix's The Glory, you know her as Park Yeon-jin — the school bully whose cruelty is so precise it borders on art. The performance was so complete that international viewers have largely frozen her image there: remote, predatory, not someone you'd want near your skincare routine.

That last detail matters.

During filming for My Royal Nemesis, Lim became increasingly worried about her co-star Heo Nam-jun's skin. Sleep deprivation had taken its toll — breakouts, dullness, the usual damage of a production schedule that doesn't respect circadian rhythms. Lim's response was not sympathy. It was logistics.

She showed up on set with her own dermatology equipment and handled it herself.

The studio audience on TEO's Salon Drip (살롱드립, a long-running Korean YouTube talk show where guests tend to be disarmingly candid) laughed for a while at that one. If Park Yeon-jin had done the same thing, it would have been a horror scene.

Lim describes herself as an 언니 collector — unni (언니) being the Korean term a woman uses for an older female friend, carrying warmth and chosen-family weight beyond its literal meaning of "older sister." She says she has always received more affection from women older than her than from those her own age. Her texting style reportedly involves an unreasonable volume of red heart emojis.

The Sweet Potato Incident at Korea's Most Competitive Arts School

Lim Ji-yeon attended the Korea National University of Arts (한국예술종합학교, known as K-Arts), the conservatory that has produced a disproportionate share of Korea's most respected film actors — including Park Jung-min and Byun Yo-han, both of whom were her classmates.

For a stretch of that time, they called her goguma.

고구마 (goguma, sweet potato) because she had developed a fixation on burgundy — specifically, the deep wine-red shade of it — and responded by wearing burgundy tracksuits from head to foot, every day. Her classmate Park Jung-min eventually looked at her and asked, flatly, whether she was a sweet potato.

She was, objectively, the color of one.

For anyone who follows Lim Ji-yeon now — the precise styling, the controlled screen presence — picturing this phase takes a moment of active imagination. That's part of what makes it land.

Cast on a Construction Site Before He Was Cast in a Drama

Heo Nam-jun's path to Netflix was less conventional than most.

Before the roles came, he was doing day labor at an apartment construction site. At some point during a shift, he was changing in the locker room when the site foreman happened to walk in. The foreman looked at him, assessed the situation, and offered him a job on the spot — bypassing the usual labor agency entirely.

The grounds for hiring: he looked like he could carry bricks.

Heo has since appeared in several Netflix productions — The Dream Life of Mr. Kim, When the Stars Gossip, and Sweet Home seasons 2 and 3. The construction site story is funny on its surface, but it points at something real: a significant number of Korean actors who now seem like polished, inevitable stars spent years in lives that looked nothing like entertainment.

The foreman wasn't wrong about the bricks, either.

What a Dating Show Taught Him About a Joseon Military Officer

In an earlier role, Heo Nam-jun played a 종사관 (jongsagwan, a royal military officer in the Joseon dynasty — roughly equivalent to a staff officer under a commanding general), and needed to find the interior stillness the character required.

He didn't study other actors playing the role. He watched Single's Inferno.

넷플릭스 솔로지옥 (Single's Inferno) is Netflix Korea's breakout dating competition — emotionally charged, very online, not a place most people would look for acting research. But Heo latched onto a specific quality in a contestant named Dex: an unshakable ease, a refusal to be rattled, emotional weather that stays clear regardless of what's happening around him.

That quality, Heo decided, was exactly what a Joseon military officer would have cultivated. The translation across four centuries and two completely different genres turns out to be coherent.

The Fight Choreography No One Sees

My Royal Nemesis (멋진 신세계, Meotjin Sinsegye) premiered on SBS on May 8 and hit Netflix globally the same day. The premise is precisely as unhinged as the viewership numbers suggest: a royal concubine from the Joseon dynasty dies by poison, wakes up in the 21st century inhabiting the body of a struggling actress, and collides with Cha Se-gye — a chaebol heir described, without apparent irony, as a monster of capitalism.

Lim plays Sin Seo-ri, the actress now possessed by a dynasty-era villain's soul. Heo plays Cha Se-gye. Their dynamic is less romance than a prolonged, well-dressed war.

The physical confrontations — slaps, collar grabs, punches that land close enough to be uncomfortable — are the result of what Heo calls 합 (hap, choreographed physical coordination, the term used in Korean performance for two bodies working in deliberate sync). Each moment was discussed and rehearsed. The two people hitting each other most convincingly on screen were, off screen, the most careful with each other.

That detail changes the viewing experience slightly.

What 9.3 Million Hours in Three Days Means

Within three days of release, My Royal Nemesis logged 9.3 million viewing hours on Netflix. In the platform's own counting — total viewing hours divided by runtime — that translated to approximately 3.9 million views. The show entered the Top 10 in 44 countries and territories, reaching #1 in Korea, Singapore, and Bolivia.

For context, K-drama's global audience has shifted. It used to arrive through algorithmic accident — Netflix recommended something, a viewer gave it twenty minutes, stayed for the season. Now viewers are looking. The fandom infrastructure exists first; the show drops into it.

Which is why a clip from a YouTube talk show matters as much as the trailer.

An actor who plays an ice-cold chaebol heir once got hired at a construction site for his physique. His co-star, a woman the world associates with choreographed cruelty, brought skincare equipment to set because a colleague's face was suffering. These are the textures that don't fit the on-screen image — and that's exactly why they travel.

Watch the episode first, then go back to the drama. The scenes where the two of them collide look a little different when you know what the rehearsal actually involved.
