Chaotic Love and Strange Stories

At a prestigious high school, in Class 2-A known for its top-tier students, a quiet and observant boy named Leo Tsukino is paired with the mysterious and intelligent Lumin Komori for a science project titled "Quantum Theory and Parallel Worlds." Working together, the two gradually open up to one another, growing closer with each passing day. Leo begins to see the fragile side of Lumin hidden beneath her composed exterior, while Lumin comes to appreciate Leo's thoughtfulness and hidden talents. As they dive deeper into their project, their bond strengthens alongside the blooming feelings between them. All the while, the classroom buzzes with the quirky antics of their classmates—Zeno, the eccentric inventor; Ken, the clumsy basketball player; Takumi, the moody artist; Iris, the cold and calculating student council president-to-be; and Himari, the cheerful, energetic girl. Yet behind their growing connection lies a greater challenge. Lumin bears the heavy burden of her family's expectations, which begins to weigh heavily on her. Then, on the day of the final project presentation, something inexplicable happens—Lumin Komori vanishes without a trace. No one in class remembers her. Not even Iris or Himari, who were supposedly her closest friends. Every record of her existence—photos, messages, even the project itself—has been altered or erased. To Leo’s horror, the science project he vividly recalls working on with Lumin is now listed under the name of Riku Lancaster, a lazy upperclassman with whom he supposedly collaborated. Caught in a whirlpool of confusion and disbelief, Leo must confront the unsettling truth: Were all his memories of Lumin just a figment of his imagination? Or is there something far more supernatural and terrifying at play?
