Rationality on a Red Thread

If the government used AI to match you with your true love, would you accept? This novel has the answer.

When love becomes a calculable optimal solution, can you still believe in the chance of a racing heart?

In 2070, the Matchmaker System governs 85% of marriages worldwide. The algorithm claims it can weave happy unions from data and replace blind chance with reason.

Shen Qingning is the System’s finest “red thread operative.” She designs perfect encounters for matched couples, scripts their heart-fluttering moments, and turns cold compatibility scores into genuine chemistry. Until she receives an assignment: approach Han Dong, a tech critic who publicly questions the System.

Han Dong sees through the algorithm’s true nature. “You’re not bringing people together in love. You’re manufacturing standardized emotional products.”

Shen Qingning begins to wonder whether the “fated” encounters she has designed are actually the greatest betrayal of what is real.

Meanwhile, System designer Su Ming discovers an even deeper fracture: a couple with a compatibility score of just 41% have weathered 32 years of life together, while a “match made in heaven” with a 99% score calls off their engagement on the eve of their wedding.

As the System begins matching people with hearing loss to people who can hear, and rebels to those who defend the status quo, the red threads start weaving patterns of unprecedented complexity. Is this technology’s ultimate understanding of human nature, or humanity’s final revolt against technology?

In this Tower of Babel of love, built from data, who is doing the calculating? Who is resisting? And who, in the gaps between the algorithms, has caught the one thing that belongs to humanity alone: a moment of love that cannot be calculated?
