A Joseon-era royal concubine possessing the body of a struggling modern actress may sound like a familiar time-slip setup, but it has turned into one of the biggest Korean drama success stories of 2026.
“My Royal Nemesis” (멋진 신세계), starring Lim Ji-yeon and Heo Nam-jun, premiered on SBS TV on May 8, 2026, airing Friday-Saturday nights, and streams simultaneously on Netflix. The series follows Kang Dan-shim, a historically reviled Joseon royal concubine executed by poison, whose spirit awakens 300 years later inside Shin Seo-ri, an overlooked actress playing minor roles in period dramas — setting up a love-hate rivalry with Cha Se-gye, a scarred and ruthless chaebol heir played by Heo.
In its first week, the show ranked No. 1 on Netflix’s global Top 10 Non-English chart, drawing 3.9 million views between May 4 and May 10, and landed in the Top 10 in 44 countries spanning Asia, Europe and South America. According to entertainment outlet Newsen, that made it the first SBS Friday-Saturday drama ever to reach No. 1 on Netflix’s weekly global non-English chart during its debut week.
Domestic ratings climbed steadily alongside the streaming numbers. According to Nielsen Korea, the show opened with a 4.1 percent nationwide rating for its first episode on May 8, then rose episode over episode, hitting a nationwide first-place ranking with 9.5 percent by its fifth episode on May 22, and reaching 10.4 percent by its eighth episode on May 30. By late May, the drama topped both TV and OTT buzz charts on Good Data Corporation’s FUNdex within three weeks of release, with Lim and Heo ranking second and third, respectively, in cast popularity.
Critics have been especially taken with Lim Ji-yeon’s dual performance. Writing for South China Morning Post, critic Pierce Conran praised her “spirited performance” as both the Joseon-era villainess and the modern-day actress, calling her fish-out-of-water comic timing and dialect delivery a highlight, while noting the drama’s central romance would need to sustain momentum once its historical-to-modern novelty wears off. A Cine21 review separately praised the show’s feminist reworking of a maligned historical figure, describing Dan-shim as one of the more proactive time-travel protagonists in recent Korean television.
The show is directed by Han Tae-seop, known for “Hot Stove League,” and written by Kang Hyun-joo, with production handled by Studio S, Studio Dragon and Gill Pictures.
