I Transmigrate into a Book Set in the 1990S, and My Desk Mate Is the Villainous Big Shot?

[Transmigrate into a book + period drama + school life + face-slapping + feel-good power fantasy + academic genius + redemption] Xu Yixiao transmigrates into a book, becoming a pretty but useless girl in the 1990s. Her father died in the line of duty, her mother is timid, and her relatives are shameless. She trusted the wrong people and is constantly dodging debt collectors. Her only worth in the original story is that she funds the heroine’s education before she dies. Xu Yixiao: ??? Author, do you want to feel the rage of a tool character who’s awakened to herself?! She has barely arrived when her cousin’s family tries to steal her place at the vocational high school attached to the machinery factory.

Xu Yixiao’s thinking is simple: this villain is capable and handsome, a good kid who’s gone astray. She’ll set him straight, and then she can count on him later. But the more she helps him, the more the villainous genius’s gaze starts to change… Her awful relatives assume that with Xu Yixiao’s terrible grades and love of trouble, she’ll get kicked out of No. 1 High School, find some disreputable job, marry a loser, and spend the rest of her life that way. But as they wait, Xu Yixiao becomes a regular student. Xu Yixiao comes first in her exams. Xu Yixiao gets into a prestigious university in the capital with that delinquent everyone talks about, and reaches the pinnacle of success… The awful relatives: ???
