Shanyue didn't know how Ye Qianze could be so ruthless. He did not care about Xiangyuan's feelings at all. What did he take Xiangyuan for?
My answer may not be accurate or complete. From what I know, Ye Qianze's feelings for Xiang Yuan are complicated. At first, he only had a good impression of Xiang Yuan, but as the plot progressed, he gradually realized that he had deeper feelings for Xiang Yuan. Ye Qianze's actions seemed cold and cruel, but in fact, there were contradictions and inner struggles when he treated Xiang Yuan. He didn't completely ignore Xiang Yuan's feelings. Instead, he chose a relatively cold way to deal with their relationship in order to protect his feelings and dignity. Ye Qianze treated Xiang Yuan as a kind of emotional sustenance and venting, and at the same time, he hoped to gain Xiang Yuan's approval and acceptance. Therefore, he sometimes showed a cruel and cold side, but in fact, he also had complicated emotions and contradictions in his heart.
