The Heir's Dominant Moment

"Gu Zhizhi, the real young lady of the family, was raised outside. In the three years after being taken back home, she was constantly oppressed by her family because her grades were lower than Gu Sisi, the fake young lady. She was even forced to marry a disabled man for a political marriage. By chance, Gu Zhizhi discovered that Gu Sisi had used mysterious means to bind their scores together, making her own grades always 200 points lower than the fake daughter’s. Gu Zhizhi decided to use this ""200-point rule"" to launch a total counterattack in the national college entrance exam and break free from the marriage. In the end, Gu Zhizhi used her wits to expose the fake daughter’s schemes, left her toxic family, and achieved true self-growth."
