This is a ridiculous novel. The male lead wiped out the female lead's entire family for the sake of the supporting female character, and even plunged the world into misery. But in the end, he didn't live happily ever after with her, because she liked the third male supporting character?
When the plot starts over, the darling of Heaven's Will assumes she's the "female lead."
Transmigrated male lead: Even if my noble status is false, even if I have no next life and my soul is scattered, I will never be the murder weapon in the supporting female character's hands.
Second male lead: I was willing to turn against the whole world for you, yet you wouldn't give me even a shred of sincerity.
Third male supporting character: I said the county magistrate killed my whole family, and you said you'd kill the emperor for me and overthrow the imperial authority?
The true female lead, a judge of the underworld: Desire and ambition burn like a raging fire, capable of destroying everything. I sentence the "female lead" to death. Heaven's Will refuses, but it can't stop the "female lead" from bringing about her own ruin. When lives pile up and resentment pierces the heavens, even Heaven's Will will protect its own reputation and cut off the female lead's fortune.
This is a contest between Heaven's chosen darling, an underworld judge, and the characters in the plot. In the end, who will get to write the rules?
