Treating Mr. Lu as a Substitute, He Broke the Defense After Finding Out

[Male stand-in + love at first sight + rich CEO + sweet pet + a noble male protagonist who is willing to be a substitute after breaking the defense vs a cold female protagonist who wants to take revenge on her scumbag father] Xu Zhouyue first had an unrequited love for Yang Jiaming, a senior in the same department in the eyes of others, and spent four years with no results. Later she met Tiansheng CEO Lu Shishen, and the two fell in love secretly. But no one knows that there is a Bai Yueguang hidden in her heart. Lu Shishen was born in Beijing and founded Tiansheng in Jiangzhou. He fell in love with Xu Zhouyue at first sight. It wasn't until he saw the portrait in the studio that he realized that what he thought was a happy relationship was actually wishful thinking. In Xu Zhouyue's eyes, he was just a stand-in! Looking at the broken photo frame, Xu Zhouyue lost her mind and decisively broke up with her. She returned to the Meng family and followed the arrangement to enter the Meng family. Everyone thought she was an illegitimate daughter, but they didn't know that she and the beloved eldest daughter of the Meng family were twin sisters. She hated the Meng family, and she wanted to destroy everything they cared about, just like these people had crushed her hopes. Lu Shi deeply resented Xu Zhouyue's deception, but he hated Xu Zhouyue even more for running away after unilaterally breaking up. He finally couldn't hold himself back and chased him to Meng's house. Whether he is a substitute or lends his hand to deal with the Meng family, he has so many uses. Can Xu Zhouyue not abandon him?
