I transmigrated into a book as the villainess, and my mission was to torment the male lead as much as possible.
With a few little tricks, I became the woman he could never forget, making him love me without hope of winning my heart. I trampled on his dignity, crushing and humiliating him relentlessly.
Once the job was done, I clapped my hands and prepared to leave, but the System dragged me back.
The male lead went mad and grabbed me by the throat, shouting that he would make me pay for everything I had done to him.
The System leisurely explained that I had gone too far with my earlier missions, causing the male lead to turn evil.
"Congratulations, Host, you have been upgraded to the female lead! Your mission to save the corrupted male lead begins now. The one who tied the knot must untie it. Good luck, Host!"
