On Our Wedding Night, My Mute Stand-In Wife Spoke

Abandoned by her birth mother as a child, she went looking for her family as an adult, only to be imprisoned and poisoned until she lost her voice. After escaping death, she was rescued by Jin Yanjue. Jian Xi thought she had found the right man, but Jin Yanjue had merely picked up a stand-in. Even a stand-in has dignity. When it is time for her to leave, she won't linger. She is just curious: now that everything is over and she has made her exit, why has Jin Yanjue come after her? Didn't they agree that they were only using each other and putting on an act?
