If Wishes Could Kill

If Wishes Could Kill is a 2026 South Korean horror mystery series that combines supernatural horror, high school drama, psychological thriller elements, and a mysterious wish-granting app. The Netflix limited series premiered globally on April 24, 2026, and consists of 8 episodes.

If Wishes Could Kill (2026) Overview

The story centers on a mysterious mobile application called Girigo, which appears to grant people's wishes. However, every wish comes with a terrifying consequence. As a group of high school students becomes connected to the app, they discover that their wishes may be linked to a deadly curse and predictions of their own deaths.

If Wishes Could Kill Plot

The series takes place at Seorin High School, where five friends — Yoo Se-ah, Lim Na-ri, Kim Geon-woo, Kang Ha-joon, and Choi Hyeong-wook — become involved with Girigo.

At first, Girigo appears to be nothing more than a strange wish-granting application. Hyeong-wook introduces the app to his friends after experiencing an unexpected success. But when their wishes begin coming true in disturbing ways, the students realize that something is seriously wrong.

The situation becomes even more frightening when a mysterious countdown appears. The friends begin receiving warnings connected to their deaths, forcing them to investigate the origin of Girigo before the curse claims them one by one.

As the mystery develops, the group discovers that the app is connected to a much darker history involving jealousy, resentment, friendship, revenge, spirits, and supernatural forces. Their search eventually leads them toward the original source of the curse.

What Makes If Wishes Could Kill Different?

One of the most interesting aspects of If Wishes Could Kill is its combination of modern technology and traditional supernatural horror. Instead of an ancient cursed object being the center of the story, the danger comes through a smartphone application.

Girigo turns something familiar — making a wish through an app — into a source of fear. The mysterious countdown also creates a constant sense of urgency, making the characters feel as though they are racing against an unavoidable deadline.

The series also goes beyond traditional jump scares. Its story explores friendship, jealousy, resentment, emotional trauma, and the consequences of getting what you want. Netflix describes the series as combining school-life drama, occult horror, suspense, friendship, and emotional bonds.

Is If Wishes Could Kill Worth Watching?

If you enjoy Korean horror dramas, supernatural mystery series, teen thrillers, cursed apps, psychological horror, and Netflix Korean dramas, If Wishes Could Kill is worth adding to your watchlist.

The eight-episode format also makes the series relatively easy to binge. Rather than stretching the mystery across a long season, the story uses a limited-series structure to gradually reveal the origin of Girigo and the reason behind its deadly curse.

The combination of a high school setting, supernatural mystery, technology, and horror gives If Wishes Could Kill a distinctive premise among 2026 Korean dramas.
