You live your life, don’t bother anyone, until one day a Black King from another world suddenly decides he wants children—and you get appointed as the most suitable vessel for this mission. Luckily, they messed up the location of the transfer. Now the minimum task is to survive all the adventures that land on your head, and the maximum task is to return to your warm little bed—without forgetting your fragile heart in this dark kingdom, which is just dying to jump out at the sight of a certain attractive lawbreaker. After all, people don’t just end up in prison… or do they?
