It was a long time ago that Victor was known as the Empire's Dragon-Slaying Hero. These days, he's nothing more than an ordinary priest at a church in the Kingdom's capital.
At least, that's what he thought...
Until one day, the Queen's elder sister came to see him in disguise and threatened him with a delighted smile:
"Your Reverence, you wouldn't want innocent people to get hurt by me, would you? If not, then become the father of my child. Understand?"
It sounds like an outrageous demand, but the truth is that the Queen's elder sister, who lost to her younger sister, plans to use Victor to create the strongest, most obedient child and overthrow her sister's reign.
Unable to let innocent people suffer because of him, Victor has no choice but to become the wicked elder sister's secret lover.
But just as Victor decides he has to stop her plot,
a mysterious woman, her face hidden but unmistakably Her Majesty the Queen, comes to him seeking punishment and asks Victor to judge her sins.
It turns out that even the seemingly cold and aloof Queen longs for someone who understands her.
And so Victor becomes both an accomplice in the wicked elder sister's plot to overthrow her younger sister and the secret rendezvous partner of the Queen, a woman with an obsessive love.
To keep more people from getting caught up in the battle between the royal sisters, Victor must offer both body and soul to comfort them, while making sure neither knows the other exists.
You could say that the peace of this country rests entirely on Victor's efforts to keep things balanced behind the scenes.
But Victor has to get out of this twisted secret relationship as soon as possible...
Because his ex-wife is a yandere. If she finds out that Victor is doing this after their divorce, it'll definitely spark a new war!
