Any defiance of this arrangement carries grave consequences. For Yukari Nejima, an unassuming teenager who perceives himself as average in every aspect, this intricate system presents a golden opportunity for a fulfilling life. Seized by an overwhelming infatuation for his classmate and long-standing crush, Misaki Takasaki, Yukari dares to defy the established norms and musters up the courage to confess his heartfelt emotions. Initially hesitant, Misaki succumbs to her own desires and reciprocates his affection in a passionate moment of surrender. Unfortunately, before the budding romance can blossom further, Yukari receives an unexpected marriage notice, thrusting him into a perplexing realm of love and deceit, as his assigned partner, Ririna Sanada, becomes undeniably fascinated by his clandestine affair.
