Chaotic Love and Strange Stories
In classroom 2-B, Leo Tsukino, a disenchanted high school student leading an ordinary life, has his world transformed when a random drawing pairs him with Lumin Komori, the mysterious beauty known as the "Ice Queen" of their school, for a science project. Assigned to study "Quantum Theory and Parallel Worlds," Leo discovers Lumin's astonishing knowledge of the subject. Their initially cold interaction gradually warms into friendship and potential romance. However, strange events unfold when Lumin suddenly vanishes without a trace—and more disturbingly, no one remembers she ever existed, not teachers, classmates, or even school records. Leo alone retains memories of her and believes in her existence. Armed with only a quantum theory notebook and their shared memories, Leo embarks on a quest to discover what happened to Lumin, supported by his friends Ken, Takumi, and Zeno—though they aren't sure who Leo is searching for. This investigation leads him to uncover secrets about the Komori family and a dangerous experiment potentially linking multiple universes. As his feelings for Lumin deepen and the line between reality and fantasy blurs, Leo must decide whether to trust his instincts or accept the world around him—as if his memories might be fragments from another parallel world entirely.
