“You shouldn’t be so self-centered. You’re lucky that Mr. Mu wants to marry you. You have no right to turn him down!” Bei Shuo felt cold on the inside after hearing what her father said. Having gone missing when she was a child, Bei Shuo was found a month ago. Before she found her biological parents, she always thought she’d have a loving family. However, when she finally returned home, she realized they had adopted another girl long ago. After more than a decade, the girl had replaced her completely. Her parents, her brother, and her fiance…

The Bei family never showed her any form of affection. On the contrary, they wanted her to marry Mu Ci for their own benefit after she had just returned. Everyone in the city knew that Mu Ci wouldn’t live long. Besides, he had an aggressive personality. Anybody who offended him would suffer badly. Bei Shuo would probably end up dead without even knowing what caused it. Hence, when she married Mu Ci, everyone in Empire City waited for news of the horrible ending. To everyone’s surprise, she actually cured him, and he even ended up pampering her! At the same time, it was revealed that Bei Shuo was actually the disciple of a miracle doctor, a top-tier hacker, a champion racer, and the founder of an international fashion brand…

On top of that, wealthy tycoons, talented directors, and e-sports professionals all spoke fondly of her. “Everyone, please allow us to introduce our favorite junior!” The man who was rumored to be cold and violent pressed his head against Bei Shuo’s shoulder when he found out about her countless identities. “How many more identities do you have?” he asked with a pout. Bei Shuo ran her fingers through his hair and smiled. “There’s only one left, and it’s the most important one. I’m still Mrs. Mu!”
