Tang Zhiyi and Gu Jingxing have been married for five years, but they don't love each other. Gu Jingxing regarded Tang Zhiyi as a stand-in for the "White Moonlight" Tang Weiwei, and Tang Zhiyi, because her lover Gu Xingzhi's heart was in Gu Jingxing. Gu Jingxing was cold and heartless to Tang Zhiyi and even abandoned her because of Tang Weiwei's appearance. Tang Zhiyi also endured Gu Jingxing's coldness because of Gu Xingzhi's heart. She knew that this marriage was a fraud and that Gu Xingzhi's heart was not with him. Tang Zhiyi resolutely decided to leave and discovered that Gu Xingzhi's death was related to Tang Weiwei. She began to pursue the truth.
