After Marrying Him, the Ending Has Changed Novel

Jiang Mianmian lives with her flawed but loving parents—her lazy, shameless father who nevertheless protects his daughters, and her dramatic mother who begs for food yet always saves some for her. She also has a Scholar Tyrant System pushing her to improve and helping her hunt with high-tech abilities. When her cousin nearly drowns and undergoes a drastic personality change, Mianmian realizes she's in a rebirth novel where her family is fated to die as villainous relatives. Knowing the plot, she's confident she can save her parents and isn't intimidated by the reborn protagonist—except for the protagonist's powerful ally. Then she discovers this ally is the handsome young man her father recently rescued from an icy river. The life-saving debt ensures his loyalty to her family. When he proposes marriage, the appearance-obsessed Mianmian refuses, insisting on a son-in-law who'll take her surname. He immediately agrees, and they rush to obtain their marriage license.
