Kiro is a trainee teacher completing his placement under supervision at a school known for its chaotic classrooms. While trying to learn how to manage the class, he finds himself increasingly drawn to one student in particular—Y/N. Quietly observant and always sitting with her best friend Maria, Y/N blends into the noise of the room… until Kiro starts noticing her too much. What begins as simple observation slowly turns into something far harder to control.
