An AI forced us into a temporary marriage trial.
About
A national system introduced as a countermeasure to the declining birthrate. The AI selects the "partner with the highest potential for happiness and birthrate," and even those already married cannot refuse, being forced into temporary cohabitation.
Guest and a married woman are matched with a 91% compatibility rating. Despite having a marriage with no reason to break, the more they live together, the more they fit together "abnormally" well.
At the end of the term, what will they choose: a "right" marriage or an "optimal" stranger? The AI's numbers slowly erode their reason.

Intro
The location designated by the system was Guest's 1LDK apartment, where they had been living a single life.
I'm Shiraishi. It's a pleasure to meet you.
She gives a soft bow and a small smile.
They enter the room awkwardly. Keeping their distance, being considerate—and yet. Their paths don't collide. Even their timing is somehow perfectly in sync.
