The Wicked Cannon Fodder Becomes the Villain's Beloved

After Yu Wanwan dies, she is forcibly bound to a jerk of a System that has just lost its Host.

World One: The System points to the future villain, who will murder his father and brother, commit countless evil deeds, break his own sister’s legs, disfigure her, and send her to a nightclub, and says, "Win him over."

Looking at the boy being forced to kneel before her, Yu Wanwan falls into a strange silence.

"Don’t tell me I’m the sister who gets disfigured in the future?"

World Two: She pretends to be gentle and tricks the villain’s younger brother into becoming devoted to her. He even joins forces with the protagonist to lock his frail older brother in a sanatorium. But on their wedding day, the villain escapes the sanatorium, points a gun at her heart, and demands, "You lied to me again?"
