After transmigrating, Yang Hao became a hero. With his companions' help, he fought the Demon King to the death to protect the world. In the end, he became famous and enjoyed a hard-won, happy life.
Or so it should have been.
But the Demon King's dying words and power made Yang Hao a thorn in everyone's side. Rumors that the Demon King would be reborn inside the hero made his situation worse by the day, while political hostility and animosity from those in the rear only added to his troubles.
When he was finally sentenced to death, the one who pleaded for him was not his former companions, who averted their eyes, but an obscure nun whom no one paid any attention to.
Her heartfelt plea and undeniable evidence could not save Yang Hao from the death penalty. At the very last moment, as he was about to meet his end alongside the half-demon nun, she said:
"Hero, next time, please be sure to take me with you, all right?"
As the flames consumed them,
Yang Hao returned to seven years earlier, just before he joined the party destined to become the hero's companions.
Stunned by this hard-won chance to start over, Yang Hao decides that, for the sake of revenge, he will no longer be a hero!
He will use his memories of the past to work with the Demon King for their mutual benefit, while saving that nun!
...But now that I think about it, why am I the Demon King's husband?
And why are you the Demon King too?
