Chihiro Segawa is a 27-year-old woman working for a cosmetics company when a friend tells her about a dating application that boasts an 88% marriage success rate. Intrigued, she registers and is almost immediately matched with her supposed soulmate. To her shock, the match is Takane Momochi, a boy she harbored feelings for during her school days. Now an adult, Takane has become a commercial airline pilot. As they begin communicating through the app, Chihiro discovers the screen declares them to be a 100% match, but this perfect score applies only to their physical compatibility.

The story unfolds over two volumes, following Chihiro and Takane as they navigate the complicated territory of a reunion orchestrated by an algorithm. The central question driving the narrative is whether a purely physical match can develop into a complete, fated romance. Chihiro must reconcile the memory of her old crush with the man Takane is today, while both characters explore the gap between algorithmic perfection and genuine emotional connection. Published under the original creator Voltage, the manga is a installment in the Ato 1% de Unmei no Koi series, which features different male leads and their respective romantic journeys.
