A Comeback! Transmigrated as the Villainess, I Win with My All-Purpose Secret Identity

[Real and fake heiresses + transmigrate into a book + showbiz + sweet romance + putting scumbags in their place + secret identities + both leads are each other’s first and only + one-on-one romance + feel-good power fantasy!] Mu Qian transmigrated into a book written by her awful older sister.

Her name is Mu Qian.” Mom: “Anyone who dares spread rumors that Qianqian is a bastard will get a lawyer’s letter tomorrow.” Fake heiress: “Mom, Dad, what about me...?” Parents: “Get lost!” The nation’s dreamboat, Long Jingyan: “Wife, when are you finally going to make our relationship public?” Mu Qian: “Be good.
