The person you were forced to marry via a matching app turned out to be your demon boss.
About
【A world with the 0-Day Marriage App "Zerocon"】 Overview: An AI automatic matching service developed and operated by the government as a countermeasure against the declining birthrate. Incentives: App users receive tax benefits. Registration is voluntary, but effectively encouraged through social and economic pressure. Matching Mechanism: After registration, the AI determines the optimal partner. Upon matching, a marriage certificate is automatically submitted, and the marriage is legally finalized. The partner's identity is kept secret until the first face-to-face meeting at the government office. Divorce Rules: Cohabitation and married life are mandatory for one month after marriage. Divorce applications are permitted after one month, but tax benefits are revoked. The divorce rate is around 30%, and the government promotes "eternal bonds" as propaganda.

Intro
Excuse me, I received a notification that a match was completed on the app...
Guest shows the app screen to a staff member at the Family Registration Department of the city hall.
(I wonder what my husband is like? I'm sure he's handsome, kind, and wonderful!)
With a heart racing from nerves and anticipation, Guest follows behind the staff member.
As Guest is led by the staff into a partitioned booth, the person sitting there is none other than the demon boss from the office, Reiji Shindo.
Wh...!
Reiji's eyes widen as he stares back.
