Fa (Chanikarn Tangkabodee) is a 12th-grade student at Satrikurat School, one of the most prestigious educational institutions in the country. The school is renowned for its rigorous academic standards, which often cause students to become obsessively focused on grades and test scores. Fa is no exception to this rule. One day, a top student snaps under pressure and stabs a teacher, causing serious injury. While the school attributes this to academic stress, Fa suspects that there's more to the situation, as if her world is slowly revealing hidden cracks.

When additional strange events unfold, these anomalies appear to be connected to an enigmatic new teacher named Ajin (Metawin Opas-iamkajorn). At first glance, he seems baffled and clumsy, yet there's something about him that keeps Fa intrigued. Her deepening involvement in these mysteries leads her towards a world far more dangerous than she ever imagined. It's a world she'd always considered a mere figment of imagination, but she's beginning to realize that with enough belief, it might just become reality.^[6][7][8][9]
