Casting aside the fact that Qin Zhi'ai and Gu Yusheng were about to become a couple, even if they had broken up, he would still clarify with the world that he had nothing to do with Liang Doukou.
Honestly speaking, if he hadn't been aware of Liang Doukou's past evil deeds, he would never have thought of addressing matters in such a roundabout way.
Furthermore, now that his grandfather was critically ill, if he were to clarify matters, it would potentially stir up anger in his grandfather again, which would not be good for his condition.
Because Liang Doukou had started this, she should not blame him for returning the volley. The best solution that he could think of was to force Liang Doukou to beg him to clarify matters.
Thus, he had intentionally made Xiaowang leak the fake news that he was already married to Liang Doukou. Combined with the previous news milestones about their relationship, almost everyone would believe this story.
