11th grade, Class 2-D. One day, a mysterious ranking list of the homeroom teacher and all 24 students is sent via text message to everyone in the class. No one knows who made it or what criteria it was based on. At the top of the list is always Tsubaki - a model student, kind and universally loved. But six months later, Tsubaki is found dead in the school bathroom, an apparent suicide. After the funeral, the students return to class - only to find an envelope left by Tsubaki on each of their desks. The school, as a confined space, functions like a micro-society - a complex stage where emotionally unstable and immature individuals are entangled. As the contents of Tsubaki's letters begin to reveal hidden truths and personal secrets, the facade of harmonious relationships begins to crack. With each letter unveiled, the delicate balance of the class shatters like ripples spreading from a single stone cast into still water. This chilling psychological school drama stands out for its intricately constructed characters and the compelling performances that bring their emotional landscapes to life. A cold, unflinching look at human nature and the painful truths that lie beneath the surface. (Martin LEE)
