What Is If Wishes Could Kill About?
The story follows five close friends studying at Seorin High School whose lives change forever after discovering a mysterious application known as Girigo.
The app appears incredibly simple.
Users only need to record themselves stating their name, date of birth, and a wish.
The wish comes true.
But exactly twenty-four hours later, the person who made that wish is hunted by an invisible vengeful spirit that slowly drives them toward a gruesome death.
The curse spreads like a deadly chain letter.
The only way to temporarily stop one person’s countdown is for someone else to make another wish, unknowingly passing the curse to a new victim.
As more students become trapped, the group begins uncovering forgotten school tragedies, bullying, hidden betrayals, and ancient Korean shamanic rituals connected to the app’s terrifying origin.
Episode 1 Explained: The First Wish Starts the Deadly Curse
The series opens several years before the main story.
A girl named Do Hye-ryung walks into an abandoned factory carrying her phone.
She carves both her name and date of birth into a wall before opening the mysterious Girigo app.
Following the app’s instructions, she records a video stating her identity and makes a horrifying wish.
She wishes for everyone who wronged her to die.
Moments after recording the wish, she calmly slits her own throat while the phone continues recording.
Her death becomes the catalyst for everything that follows.
Meet the Main Characters at Seorin High School
The story then shifts to present-day Seorin High School.
The central group consists of five close friends.
Yoo Se-ah is a determined track-and-field athlete who lost both of her parents in a tragic car accident years earlier. She now lives with her aunt, who works as a nurse.
Kim Geon-woo is Se-ah’s caring boyfriend, although the two keep their relationship secret.
Lim Na-ri is one of the school’s popular girls, but beneath her confident appearance lies deep insecurity. Unknown to everyone else, she secretly has feelings for Geon-woo.
Kang Ha-joon is the analytical, tech-savvy member of the group who often approaches problems logically.
Choi Hyeong-wook, sometimes referred to as Yong-wook, struggles academically and frequently feels overshadowed by everyone around him.
The Girigo App Appears
Everything changes when Hyeong-wook discovers the Girigo app through an online Discord acquaintance named Min-soo.
Desperate to improve his grades, he follows the app’s unusual instructions.
Standing before his phone, he clearly states his name, birth date, and wishes to receive a perfect score on his upcoming mathematics examination.
The impossible soon happens.
He scores one hundred percent.
The app has actually granted his wish.
Excited and unable to believe his luck, Hyeong-wook sends the application to his friends.
Most dismiss it as nothing more than an internet prank.
However, shortly afterward, a mysterious twenty-four-hour countdown suddenly appears on his phone.
The Curse Slowly Takes Control
As the timer continues counting down, Hyeong-wook begins receiving disturbing phone calls.
Instead of hearing ordinary voices, he hears recordings that sound exactly like his closest friends cruelly mocking and insulting him.
Whether these voices are real or supernatural becomes increasingly unclear.
His personality rapidly changes.
Fear, paranoia, and anger completely consume him.
At the same time, Geon-woo jokingly installs the app himself.
Wanting more time with Se-ah and their friends, he casually wishes for Se-ah’s upcoming national athletics practice to be canceled.
He treats the entire process like harmless entertainment.
Unfortunately, the app accepts his wish.
Episode 1 Ends with a Brutal Death
Hyeong-wook’s mental condition reaches its breaking point during class.
Possessed by an invisible force, he suddenly attacks his classmates, focusing particularly on Se-ah.
Moments later, in one of the series’ most shocking scenes, he slits his own throat with a knife in front of everyone.
As Se-ah desperately tries to save him, the countdown reaches zero.
Hyeong-wook dies.
The horrifying death leaves the entire friend group traumatized while confirming that Girigo is far more than a harmless smartphone application.
Episode 2 Explained: The Curse Spreads to the Next Victim
Following Hyeong-wook’s death, the authorities officially classify the incident as suicide.
But Se-ah struggles to accept such a simple explanation.
Almost immediately, another impossible event occurs.
Her national athletics practice is suddenly canceled.
It exactly matches the wish Geon-woo casually made the previous day.
The realization is devastating.
The app truly grants wishes.
Soon afterward, Geon-woo’s own twenty-four-hour countdown appears.
The curse has selected its next victim.
Childhood Memories Reveal Their Strong Bond
The episode also explores the group’s past.
Flashbacks reveal that their friendship formed after Se-ah lost both of her parents in a fatal car accident.
Her friends became the emotional support system that helped her continue moving forward.
This emotional history makes the supernatural threat even more devastating because every new victim tears apart relationships built over many years.
Geon-woo Begins Losing Control
The group desperately searches for ways to remove the app.
Nothing works.
The application refuses to disappear.
Meanwhile, Geon-woo begins displaying exactly the same disturbing symptoms that Hyeong-wook experienced.
His personality changes dramatically.
He grows violent and unpredictable.
Na-ri secretly records his frightening behavior while the others attempt to calm him.
Instead, Geon-woo attacks Ha-joon and Se-ah before finally being subdued.
He is rushed to intensive care, but even inside the hospital, the curse refuses to release him.
Korean Shamanism Enters the Story
At this point, the series expands beyond technological horror.
Ha-joon’s older sister, Haetsal (also referred to as Hyang), enters the story.
She is a powerful shaman who immediately recognizes the signs of a dangerous vengeful spirit.
She urgently warns Ha-joon that everyone connected to the Girigo app is in terrible danger.
According to her, this is not simply a haunted application.
A powerful supernatural entity is manipulating every victim.
Se-ah Makes a Sacrifice
Watching Geon-woo slowly die, Se-ah refuses to give up.
She records her own Girigo video.
Instead of asking for personal success, she wishes for Geon-woo to survive.
The app grants her wish immediately.
Geon-woo stabilizes.
His countdown stops.
But the curse has not disappeared.
It has simply moved.
A new twenty-four-hour timer now appears on Se-ah’s own phone.
The chain continues.
Na-ri eventually discovers the frozen countdown and realizes the terrifying truth.
Every new wish merely transfers the curse to another person instead of destroying it.
Episode 3 Explained: Se-ah Enters the Spirit Realm
With her countdown running, Ha-joon takes Se-ah deep into the mountains to meet Haetsal properly.
She lives there with her husband and fellow spiritual practitioner, Bangwool (also called Bang-yeol in some accounts).
Together they prepare an elaborate ritual unlike anything the group has previously witnessed.
Before the ritual even begins, Se-ah receives a phone call.
The caller sounds exactly like Geon-woo.
But it is only another trick created by the vengeful spirit attempting to lure her toward self-destruction.
A Journey Into Another World
Haetsal decides that ordinary protection is no longer enough.
She performs a dangerous ritual that sends Se-ah’s soul into the cursed spirit realm.
She gives one simple warning.
Find the exit.
Never look back.
Inside this terrifying dimension, Se-ah is forced to relive the darkest moments of her life.
She witnesses Hyeong-wook’s horrifying suicide all over again.
She is also forced to relive the tragic accident that killed her parents.
The spirit even disguises itself as her dying mother, hoping emotional manipulation will keep Se-ah trapped forever.
Throughout the ritual, Haetsal guides Se-ah using a sacred white thread connecting both worlds.
Haetsal Pays a Heavy Price
Se-ah almost escapes.
Just before reaching safety, however, the spirit creates one final illusion.
She is tricked into turning around.
That single mistake nearly traps her forever.
Realizing what has happened, Haetsal enters the spirit realm herself.
She successfully rescues Se-ah but pays an enormous personal cost during the ritual.
Although Se-ah returns safely to reality, Haetsal explains that the curse has not ended.
Instead, it has become even more dangerous.
That same night, supernatural attacks begin once again.
Episode 4 Explained: The Truth Behind Girigo Slowly Emerges
The fourth episode transforms into a mystery investigation.
After suffering nightmares involving two ghostly schoolgirls, Se-ah joins Ha-joon and Bangwool in searching for the true origin of the Girigo app.
Their investigation leads them toward two names connected to past tragedies:
Do Hye-ryung
and
Kwon Si-won.
Both girls appear deeply connected to the supernatural events surrounding the app.
Mysterious Clues Lead to the Past
The group follows clues left behind by Hyeong-wook, including information stored within his Discord conversations.
This eventually leads them back to Min-soo, the online acquaintance who first introduced Hyeong-wook to Girigo and had also supplied him with pills.
Min-soo already knew the application was dangerous.
Searching Hye-ryung’s abandoned home uncovers disturbing evidence of ancient spiritual rituals.
Inside they discover talismans, preserved hair, ritual objects, photographs, and multiple signs pointing toward vengeful spirit practices.
Everything suggests Hye-ryung’s family possessed deep knowledge of Korean shamanism.
Na-ri’s Secret Changes Everything
While searching the school’s computer systems, Se-ah and Ha-joon uncover one of the season’s biggest revelations.
Na-ri had secretly used the Girigo app long before anyone realized the curse was real.
Her recorded wish asked for the deaths of Hyeong-wook and another student she found annoying.
This explains why she remained alive while others became victims.
She unknowingly pushed the curse forward onto someone else.
Meanwhile, a recovering Geon-woo escapes the hospital and reunites with Na-ri, unaware that Se-ah and Ha-joon have uncovered her devastating secret.
The discovery threatens to completely destroy the group’s trust.
The Biggest Revelation So Far: How Can the Curse Be Stopped?
Haetsal finally explains the supernatural foundation of Girigo.
The evil spirit is connected to a maehyung, a physical object anchoring it to the human world.
Evidence strongly suggests that this object is a mysterious red phone once owned by Hyeong-wook—or more specifically, Hye-ryung’s phone seen repeatedly during visions.
Destroying the app alone will accomplish nothing.
The anchor itself must be recovered from the spirit realm and destroyed.
Only then can the cycle finally end.
As Episode 4 concludes, Se-ah realizes she must once again enter the terrifying supernatural world to retrieve the maehyung before more of her friends become victims.
But with Na-ri’s betrayal now exposed and the vengeful spirit growing stronger, the battle has only just begun.
The first half of If Wishes Could Kill masterfully blends psychological horror, emotional character drama, technological paranoia, and traditional Korean shamanism into an increasingly complex supernatural mystery. Rather than answering every question, Episodes 1 through 4 carefully reveal the curse piece by piece while constantly raising the stakes, setting the stage for an even more dangerous confrontation in the remaining four episodes.
Part 2 continues with Episodes 5–8, where the truth behind Girigo, the complete history of Hye-ryung and Si-won, and the final battle against the vengeful spirit are finally revealed.
