Victor, a former dragon-slaying hero, was at his wits' end. He had become a priest in the royal capital of a neighboring kingdom in order to wipe out every evil dragon in the world.
But for some reason, the queen was drawn to him, and he was forced to become her secret lover.
Then the queen's older sister set her sights on his body, hoping to secretly conceive a cursed child who could overthrow the queen's rule.
He thought the queen, caught up with those two, was just as unfortunate as he was. But it turned out she also wanted to hide her identity and use him to relieve some stress.
If that were all, it might have been bearable.
But can someone tell him why they switched bodies?!
Can someone tell him why, even after switching bodies with each other, they haven't given up on their original plans?!
The queen's older sister, inside the body of the cold, proud knight queen, is plotting to kill her own original body and use magic to brainwash Victor into becoming her devoted knight and husband, ready to give everything for her.
The queen, inside the body of her bewitching, cruel older sister, is keeping a close watch on her sister while indulging herself in her sister's body and winning Victor over to her side.
The seemingly pure and dignified queen's consort takes things even further. After switching bodies with a nun, she lets the nun keep pretending to be her and carry on an affair with the queen, while she herself revels in the double thrill of forbidden pleasures.
To keep the country from plunging into chaos, Victor has no choice but to do everything he can to maintain the balance and thwart everyone's schemes.
The good news: the body swaps aren't permanent.
The bad news: they'll switch again after getting their original bodies back, and this time the four of them will swap among themselves!
The even worse news: the nun, who had lost her memories, has remembered that she was an evil dragon, and has launched a revenge campaign against him too!
