I'm In Love and It's the End of the World

Mahiru Yanase has spent her entire life living in the shadow of her twin sister, Mayo. While Mayo effortlessly commands attention with her sweetness and charm, Mahiru has resigned herself to being the overlooked sibling. To cope, she has developed a strict personal philosophy: every stroke of good fortune must inevitably be offset by an equal misfortune. By keeping her expectations low, she believes she can maintain the delicate balance of her life and avoid disappointment. However, this carefully guarded worldview is thrown into chaos on her very first day of high school. Aoi Satomi, a striking and enigmatic classmate, unexpectedly singles her out. Before the final bell even rings, he asks her out, leaving Mahiru entirely bewildered by this sudden turn of events. For someone who has never experienced such effortless luck, his attention feels less like a dream come true and more like a dangerous disruption of the universe's natural order. Now caught between the thrill of young romance and her deep-seated fear of karmic retribution, Mahiru waits anxiously for the other shoe to drop. According to her lifelong rules, something terrible must happen to counterbalance this incredible streak of good fortune. If the scales are not tipped back soon, she is convinced that the end of the world itself might be right around the corner.
