Lu Qingyan was once the perfect daughter—an obedient, soft-spoken high school girl known for her academic excellence and fragile health. But the one person she loved the most was her older brother—hentle, dazzling, and far too burdened for his age, he was her everything.. No one noticed his silent suffering… until it was too late. The day he took his own life, she shattered.

Months later, while saving a child from an oncoming car, Lu Qingyan dies and awakens inside a familiar story: the school novel "A Thorn in the Crown", one she read during her lowest days.

But she’s no longer just a reader.
She’s now Lu Qingyan, the infamous younger sister of Lu Mingxuan—the novel’s violent and cold-hearted villain feared across campus. A notorious delinquent, and ironically, the sworn enemy of her favorite character: Wang Jingyuan, the story’s tragic antagonist turned misunderstood villain.

In the novel, Lu Qingyan is little more than cannon fodder—a delusional girl who idolizes her brother, gets caught in the crossfire between Lu Mingxuan and Wang Jingyuan, and ends up being dead.

Determined to change the plot, she initially plans to curry favor with Wang Jingyuan—to save him from his doomed fate.

But everything shifts the moment she lays eyes on Lu Mingxuan.

He has her brother’s face.
The same weary eyes.
The same lonely back.
The same silent cry for help no one else hears.

And in that moment, Lu Qingyan’s plan shatters.

This isn’t just a story anymore.

So Lu Qingyan vowed to protect him this time, even if it means dragging her brother out of gang fights, squaring off against entitled rich kids, or defying the other villain himself—Wang Jingyuan, the school’s cold and brilliant golden boy... and Lu Mingxuan's sworn rival.

In the original novel, Wang Jingyuan was one of the big villains—the cunning and miserable friend of the male lead. Now, he’s front and center... and watching her a little too closely.

...

Lu Mingxuan always disliked his bootlicking sister, but one day he discovered that she had stopped following him around.

Later, he unexpectedly found his sworn enemy, Wang Jingyuan, trapping his sister against the wall and between his arms. With an ambiguous and languid expression, he coaxed in a soft tone, "Just give up on that useless brother of yours. What Lu Mingxuan can give you, I can too."

Lu Qingyan: ???

Wang Jingyuan, you dog!!

That’s my sister!! Stop daydreaming!!

——200 Basic High School Mathematics Practice Problems (2)


Lu Qingyan hesitated for a moment before asking Teacher Jia, "Then Teacher, am I handing it to you over the weekend?"


Teacher Jia, the ever-unbending man with the personality of unseasoned tofu, shook his head. "The one coming over the weekend is the teaching assistant. You can ask him any questions you have. Later, I will ask the teaching assistant about your situation."


Lu Qingyan felt that these make-up lessons had rendered counterproductivity to herself instead. In fact, when doing the assignment, she'd deliberately got a few questions wrong—just enough to avoid his suspicion—because answering everything perfectly might actually expose her.


After all, no real math-deficient student would breeze through 200 problems with flying colors.
