Betrayed me? You don't deserve it.

To annul the engagement, the aloof heiress of a wealthy family spent three years planning thirteen accidents to try and kill me.
Car accident, falling object, poisoning... I survived covered in blood, only to be met with her disgusted question: "How come you're still alive?"
She let her scheming childhood sweetheart crush my father's ashes, and even personally drained my last remaining blood to save me, all for her sweetheart's self-inflicted injury.
She thought I would be like a dog, clinging to her side forever without any boundaries.
Until that day, I calmly handed over the annulment agreement, clutching the diagnosis of late-stage brain cancer, and completely disappeared from her world.
Later, when she finally found out the truth, she searched the world frantically, only to find my emaciated, cold corpse.
That arrogant and haughty young lady has completely collapsed.
She personally sent her childhood sweetheart to hell, knelt before my body wearing a veil, and desperately raised a gun:
“Ivan, walk slowly on your way to the underworld... I’m giving my life for you.”
