In response to the decreasing birthrate, the Japanese government selected a particular high school to implement the "Bright World Project." The guidelines were straightforward: over the course of a summer hiatus, each student was required to secure a romantic companion, or else suffer grave consequences. Despite 99% of the school successfully forming partnerships, 9 students were left without a significant other. These 9 individuals must now endure the daunting "LOVE OR DEATH" challenge, regardless of their personal desires.
