The Wen family and the Ye family were family friends and had arranged a baby marriage very early, but both Wen families were boys before Ye Qingxiao was six years old. Finally, Wen Ruan was born when Ye Qingxiao was six years old. Ye Qingxiao's heart was filled with cuteness when he saw Wen Ruan for the first time, especially when Wen Ruan smiled at him, he became convinced that Wen Ruan was the only one in his life.
When Wen Ruan was a child, she loved playing with her elder brother, but when she grew up, Wen Ruan met Bai Qingyang, and she fell in love with him. She only felt affection for Ye Qingxiao as a brother. It wasn't until she accidentally saw Ye Qingxiao teaching Bai Qingxiao that Wen Ruan discovered that Ye Qingxiao's gentleness was all fake, and that he was gloomy and scary. So he decided to cancel the baby kiss with Ye Qingxiao. After Ye Qingxiao found out, he completely exposed his true nature.
