Once, he was happy by her side and had truly loved her. This love was certainly not greater than Xueru's love for him, but it was genuine, and that made him very happy.
Later on, he gradually lost interest in her for many reasons.
Xueru was too conservative, a mismatch for his character, and their interests and hobbies were entirely different. She always acquiesced to him but had nothing to talk to him about. With time, his interest faded, and coupled with the fact that Xueru couldn't give him the pleasure he desired in bed, many reasons led him to start finding her dull. Then, after meeting Han Bi, the last trace of fondness he had for her disappeared.
Over the years, he had no intention of paying special attention to news of her. Whenever he saw her appear in small sections of the media, he would think, "This is the woman I abandoned. She is unhappy and dull."
This was almost his impression of Chen Xueru.
