All along, Su Yaoqi was not only Duke Su's beloved son but also his insurmountable weakness.
Whenever anything involved this son, Duke Su could never remain calm.
Earlier, when Su Yu was pushed and sent back to her room, and the doctor declared a miscarriage, Aunt Qiu came to him immediately. It seemed she was provoked by her daughter's plight; a woman who was usually timid and prone to tears actually summoned the courage to recount Hao Yun's crimes from that night in detail.
Through Aunt Qiu, Duke Su realized he had wrongly accused his favored concubine, the Third Aunt. The real culprit was Hao Yun; even if it wasn't intentional, the harm done to Little Four was an undeniable fact.
Duke Su did not plan to report the matter to the authorities, nor did he think of killing the person directly, as that would not be enough to appease his anger.
He wanted an eye for an eye.
