The entire narrative revolves around an app called Girigo. The rules of the app are deceptively simple: users must upload a recorded video of themselves stating their name, birthdate, and their deepest desire, or input their saju (a traditional Korean fortune-telling system). Whatever the user wishes for—whether it is passing an exam, winning a crush's affection, or getting revenge—instantly comes true. However, the app acts like a digital monkey's paw. The moment the wish is fulfilled, a 24-hour countdown timer appears on the user's screen. When the timer hits zero, the user violently loses their life, usually by being possessed and driven to gruesome acts of self-harm. The series begins at Seorin High School, where a class clown named Choi Hyeong-wook stumbles upon the app. Joking around, he submits a video wishing for a perfect score on an upcoming, notoriously difficult math exam. When he unexpectedly aces the test, he thinks it is just a bizarre coincidence. Exactly 24 hours later, a horrifying, bloody freak-out in the middle of class leaves Hyeong-wook dead by his own hand. Shocked by the sudden loss, his core group of friends—including Yoo Se-ah, Lim Na-ri, Kim Geon-woo, and Kang Ha-joon—realize the terrifying connection between the app and his death.
