| If Wishes Could Kill Relationship Chart Explained: Who’s Who in Netflix’s Dark New K-Drama and Why Everyone’s Side-Eyeing the Girigo App. (Credits: Netflix) |
Netflix’s new Korean drama If Wishes Could Kill has arrived with the sort of premise that instantly makes people say, “Absolutely not,” while still pressing play. The eight-episode YA horror mystery, released in full on 24 April, follows a sinister app called Girigo that grants users their deepest wishes — then demands a deadly price. It is teenage ambition, fear, jealousy and bad decision-making wrapped into one slick thriller. In other words, a normal school week, but worse.
The series, known in Korean as 은밀한감사, leans into the chaos of modern wish fulfilment culture with a brutally simple question: if an app could fix your life overnight, would you ignore the warning label? Judging by the plot, yes. Repeatedly. And badly.
With a fresh-faced cast led by rising stars and former idol talent, the drama is already pulling viewers into its tense character web, where everyone seems connected, suspicious, or one poor choice away from disaster.
At the centre of the story is Yoo Se Ah, played by Jeon So Young. She is a talented high-school sprinter, sharp-minded and not easily rattled, which is useful when mysterious deaths start circling her classmates.
Se Ah becomes the emotional anchor of the drama after discovering that Girigo may be tied to the death of a friend. Rather than sensibly running in the opposite direction, she digs deeper. Her relationship chart places her at the centre of nearly every major connection in the series.
Close to Se Ah is Kim Geon U, played by Baek Sun Ho, her secret boyfriend and one of the characters most entangled in the fallout of Girigo.
Their hidden romance adds pressure to an already unstable situation, especially when trust becomes a luxury nobody can afford.
Geon U appears emotionally tied to Se Ah, yet dangerously curious about the app itself. That combination rarely ends well in dramas, and almost never in horror ones.
Then comes Kang Ha Jun, portrayed by Hyun Woo Seok, the logical brain of the group.
Ha Jun is the kind of student who sees cursed technology and thinks, “Let me analyse the code.” Bold move. He approaches Girigo through reason rather than panic, trying to understand its mechanics and patterns.
He is also linked to another key figure, Haetsal / Kang Ha Yeong, played by Jeon So Nee, who is introduced as Ha Jun’s sister. Their family connection could prove more important than it first appears.
Im Na Ri, played by Kang Mi Na, brings another layer to the group dynamic. Popular, polished and initially seeming detached from the darker events around her, Na Ri is soon pulled into the consequences of wish-making.
Her role suggests someone who may have entered the game thinking she could control it, only to discover Girigo does not do refunds. Mi Na’s casting also adds strong viewer interest, with many recognising her from her idol and acting career.
The wildcard is Choi Hyeong Uk, played by Lee Hyo Je. Mischievous, unpredictable and already familiar with Girigo before others catch on, Hyeong Uk may know far more than he admits.
Every thriller needs one character who smiles at the wrong time and speaks in half-truths. Congratulations to him for securing that role. His past with the app hints that some wishes are granted long before the real damage appears.

Supporting characters widen the mystery. Bang Ul, played by Roh Jae Won, is a shaman figure, which usually means either answers or more confusion. Coach Song, played by Yoon Sa Bong, likely connects to Se Ah’s athletic world.
Kwon Si Won, played by Choi Ju Eun, is listed as the developer of Girigo, placing her near the centre of the larger conspiracy. If your name appears next to “developer of cursed app”, it is usually not great press.
Other names in the cast include Cha Hee as Ji Sun, Lee Sang Hee as Eop Sun, Park Tae Rin as Lee Dong Jae, and Jo Wan Ki as the homeroom teacher. These characters may not dominate early headlines, but mystery dramas love turning background figures into key players when viewers least expect it.
The relationship chart itself is built around five students linked by school life, secrets and escalating danger. Se Ah and Geon U share a hidden romance. Se Ah and Ha Jun are connected through the investigation.
Na Ri moves between social circles and the darker pull of Girigo. Hyeong Uk stands as the insider who knows too much. Ha Jun and Haetsal add family stakes. Hovering over all of them is the app, which is less a tool and more a manipulative sixth main character.
Online reaction has been lively and mixed in the best possible way. Some viewers are praising the fast pace, bingeable eight-episode format and fresh younger cast. O
thers say the concept is so stressful it makes deleting all apps feel like self-care. Several fans are especially highlighting Jeon So Young as a breakout lead, while others are curious whether Kang Mi Na will get an even bigger dramatic arc in later episodes. A few viewers have joked that the real villain is agreeing to any terms and conditions without reading them first.
What makes If Wishes Could Kill stand out is how it mixes teen drama energy with supernatural dread. It is not just about wishes coming true, but about why people make them in the first place.
Envy, loneliness, ambition and desperation are all hiding beneath the horror. That gives the series more bite than a simple cursed-app gimmick.
With all eight episodes now streaming, viewers can map the alliances, guess the betrayals and decide which character should have simply switched their phone off on day one. Who do you trust most in the Girigo chaos, who feels the most suspicious, and which pairing are you backing?
