Netflix’s ambitious Korean original drama shot up the charts the moment it premiered, quickly becoming the center of attention.
The series is Netflix’s first Korean young-adult (YA) horror. Titled ‘Girigo,’ it deftly captures the anxiety and dread high school students experience when thrust into unpredictable, terrifying situations. Netflix released the series on April 24, 2026; it carries a 19+ rating, restricting it to adult viewers.
No. 1 in Korea, No. 3 Worldwide…Tops charts in 13 countries
Within two days of its release, the series rose to No. 1 on Netflix Korea’s Top 10 list for TV series. It vaulted past high-profile new releases such as ‘Everyone Is Fighting Their Own Worthlessness,’ ‘Sold Out Again Today,’ ‘God and the Law Office,’ and ‘Hounds.’
FlixPatrol, which tracks OTT viewing worldwide, reported on April 27 that the show reached No. 1 in 13 countries, including South Korea, demonstrating strong international interest. It placed third on the global chart.
So what kind of show is ‘Girigo’?
Released on Netflix on April 24, 2026, ‘Girigo’ is an eight-episode Korean original YA horror series. It follows a group of high school students ensnared by a curse tied to a wish-granting app. After receiving notifications that predict their deaths, the students scramble to break the chain.
When a wish is granted, the app sends a “Your wish has been granted” notification and immediately starts a 24-hour countdown. If the timer reaches 00:00:00, the person who made the wish dies. The only way to avoid this fate is for someone else to make a wish through the app before the timer expires; if that wish is granted, the curse transfers to the new wisher.
The premise—a wish app—felt fresh to viewers, and the series is entirely original, not adapted from a webtoon or novel.
Directing team carries the DNA of ‘Kingdom’ and ‘Moving’
Park Yoon-seo directs ‘Girigo.’ Park built his craft across genres and scales, serving as an assistant director on Netflix’s ‘Kingdom’ Season 2 and working on the films ‘The Admiral: Roaring Currents’ and ‘The Mayor,’ before directing the drama ‘Moving.’ CJ ENM Studios and Kairos Makers produced the series.
Park said a feature film can rely on pure scares, but a series needs narrative plausibility to sustain a longer arc. To keep all eight episodes engaging, he added occult, action and school-drama elements to the traditional horror core.
He has signaled interest in expanding ‘Girigo’ into future seasons, comparing the potential to the ‘Whispering Corridors’ anthology and saying he hopes a seasonal format could introduce promising new talent. The team is still deciding whether to continue the same storyline or explore new tales.
While the app-centered curse is a globally resonant concept, Park deliberately emphasized Korean sensibilities, arguing that local detail will likely appeal to international audiences.
Breakout newcomers — a fresh casting lineup
The series casts several newcomers in key roles, including Jeon So-young, Hyun Woo-seok, Lee Hyo-je and Baek Seon-ho. Apart from Kang Mina, who first drew attention on the audition program ‘Produce 101,’ the ensemble is largely composed of fresh faces.
Jeon So-young plays the lead, Yoo Se-a, marking her first major starring role. Represented by BH Entertainment, she previously made an impression on ENA’s ‘Honor: Her Court.’ Jeon said she poured everything into the part, adding that she trained for two months in track to portray an aspiring sprinter.
Kang Mina, who plays Im Na-ri, appears in a markedly different look—she swapped her longtime bob for long hair. Although she usually avoids horror, she said she watched scary films throughout production to build her nerve. Kang described Na-ri as a student who always draws attention at school, is fiercely possessive, and will do whatever it takes to get what she wants.
Hyun Woo-seok arrived on set early to learn coding for his role as Ha-jun, and Lee Hyo-je reportedly gained about 20 kg (roughly 44 lb) for his character.
Jeon So-ni makes a notable special appearance as Haetsal, a shaman who recognizes that the Girigo app is not a simple program but a curse born of restless spirits. Her character identifies the root of the children’s crisis and offers a lead toward resolving the mystery. Director Park said he cast Jeon to provide the young actors with a steady, experienced presence.
Viewer reactions: “I was so scared I watched the whole thing”
After the release, YouTube and online communities filled with viewer reactions. Comments included, “I binged all eight episodes in one sitting,” “Finally something fun on Netflix,” “It was much better than I expected—not formulaic,” and “The newcomers act very well.”
Many praised the show’s genre craftsmanship. One viewer wrote that they found it more enjoyable than many recent titles, praising scenes that evoke escaping the space between life and death—comparisons were made to the ‘Insidious’ series. Others noted it’s not just jump scares but a tightly plotted show: “A well-made horror series after a long time. If you can’t handle gore, skip it.” Some compared it to classic Japanese horror like ‘Ringu’ and ‘One Missed Call,’ calling ‘Girigo’ a contemporary Korean take on those traditions.
Viewers also attested to the show’s scare factor: “I watched it alone at dawn and had to turn it off because it scared me,” one wrote. “I was so scared I still can’t turn the lights off.” Several noted that the unfamiliar cast increased immersion: “The series hits hard from the start; the mostly new actors make it easier to get absorbed.”
Branded as Netflix’s first Korean YA horror, ‘Girigo’ has captured audiences beyond Korea and appears poised to open a new chapter for K-horror on the global stage.
