From what Xi Xinyi remembered, Yue Lingsi rarely told her about her past with Xi Mushan and Shen Wenna because ever since she was little, she knew that she was an illegitimate child who did not even know who her father was.
Deng Wenwen visited them frequently abroad. When they came back, Deng Wenwen would bring her over to West Park to play, and that was when she got to know Xi Xiaye.
At that time, she often saw Xi Mushan. Xi Xiaye was living in a happy family and she was really envious and hoped that she and Yue Lingsi would somehow take Xi Xiaye and Shen Wenna's place.
