After Awakening, the Cannon-Fodder Became the Beloved Female Lead

[Quick transmigration + fantasy romance + no fixed couple + both leads have no past relationships + captivating heroine, the most beautiful woman around. The author's writing is amateurish, and the first story ends badly. If you don't want to read it, don't force yourself.]

Shen Nian awakened. During the summer before her senior year of high school began, she had a dream. In it, she was the vicious supporting female character, her fiancé Quan Cheng was the male lead, and the heroine Su Xiaoxiao was a special-admissions student. Just like in a novel, childhood sweethearts couldn't compete with someone who appeared out of nowhere. In the dream, Quan Cheng fell for Su Xiaoxiao. Out of jealousy, Shen Nian bullied her at school. In the end, the Shen family went bankrupt, her parents died in a car accident, and Shen Nian, utterly despairing, jumped from the rooftop. The Shen family was destroyed, and everyone in it perished. Shen Nian woke up in terror, but she had also awakened. She wouldn't let the dream come true. She would be the protagonist of her own life.

After awakening, Shen Nian was bound to System 649863937 and began her quick transmigration journey.
