Unmei wa Yaku ni Tatanai

On an ordinary day, the world was irrevocably transformed. Without warning, a delicate crimson thread materialized around the ring finger of every human being across the globe. It soon became clear that these threads were no mere anomaly; they were physical manifestations of destiny, linking each person to their one true partner and guaranteeing a lasting relationship. Overnight, society restructured itself around this celestial matchmaking system. Dating rituals evolved, marriages were legitimized by the presence of the thread, and the ancient legend of the "red thread of fate" became a tangible, everyday reality. Love, once a chaotic and uncertain pursuit, was now a visible certainty—and a new era of thread-based romance was born. Yet, amidst this global celebration of predestined love stands Tsumugi, a young woman who holds nothing but contempt for the system. She scoffs at the idea that a simple strand of silk could dictate the heart's deepest affections, viewing the threads as a gilded cage rather than a gift. Her principled rejection of thread-based courtship has made her an outlier in a world obsessed with cosmic compatibility. That is, until the moment a red thread of her own unexpectedly coils around her finger. Forced to confront the irony of her situation, Tsumugi must now grapple with a profound dilemma: is her disdain for fate merely stubborn pride, or can she truly defy a bond that the entire world believes to be unbreakable? Her journey begins as she decides to challenge the very system that has just claimed her as its own.
