She Hides Her Wicked Intentions, and the Cool Young Heir Willingly Becomes Her Devoted Servant

After Lin Yun is reborn, she discovers that her stupid, wicked cousin has been reborn along with her. The first thing her cousin does is try to switch their marriages.

Lin Yun: "You want to marry that dog emperor? Fine, I'll let you. As for the man you married in your last life, forget it. I don't want him."

Unfortunately, just as she tries to keep her distance, her brother-in-law starts clinging to her.
