Yukito Takiguchi is an unpopular science college student who has poured his efforts into developing the ultimate matchmaking system. His creation, a sophisticated algorithm designed to calculate perfect romantic compatibility, takes an unexpected turn when a woman materializes before him, claiming to be his future wife. This sudden and inexplicable arrival launches Yukito into a science-fiction romantic comedy where the logic of data and algorithms collides with the unpredictable reality of human relationships.

The story centers on Yukito, whose background in scientific rigor makes him ill-prepared for the chaotic arrival of this self-proclaimed bride from the future. The mysterious woman who appears before him is determined to make their destined marriage a reality, forcing Yukito to confront a future he never anticipated. Their initial encounter sets the stage for a relationship built on equal parts skepticism and genuine curiosity, as the pragmatic student must navigate the complexities of love through the lens of his own creation. The manga follows their evolving dynamic as Yukito tries to reconcile his algorithmic understanding of compatibility with the living, breathing woman who insists they belong together.

Written by Yasunori Mitsunaga with art by saku, the series blends futuristic technology with classic romantic comedy tropes. The narrative explores what happens when data-driven predictions meet the messy, unpredictable nature of genuine human emotion. As Yukito spends more time with his supposed future wife, he begins to question whether his perfect system can account for the intangible aspects of love, such as fate, choice, and the simple act of falling for someone unexpectedly.

The manga launched in Shueisha's Grand Jump Mucha magazine on April 23, 2025, marking the beginning of Yukito's journey as he discovers that the algorithm for a happy future may not be as straightforward as he once believed.
