Reborn in the 1970S: The Cannon-Fodder Villainess Has Space

Du Yuewei never expected that after being shoved into a horde of zombies, she would accidentally end up inside a period novel, as the lazy, gluttonous, vicious supporting character who mistreated her younger brother-in-law and sister-in-law. Du Yuewei curses her luck, but what else can she do? When faced with a domineering sister-in-law, she becomes even more domineering. When faced with a vicious mother-in-law, she becomes even more vicious. Despite the poverty of the era, Du Yuewei lives in comfort thanks to her personal space. But when did the brother-in-law who hated her become her lackey, the sister-in-law become her biggest fan, and the man following her around show up?
