Cao Yujin didn't want to trust her intuition. But the scene earlier of the three having so much fun and enjoying their time like the perfect picture of a family became an eyesore to her.
She had always viewed herself as Song Yu Han's wife ever since she laid her eyes on him. Although Song Yu Han's mother was not the first wife and an official one, turning him into a child out of wedlock, he was still the young master who had been under the tutelage of the Old Patriarch Song. This means a lot to several people.
Old Patriarch Song particularly didn't like being dragged into a mess that he didn't want to solve. His son's messy romantic affairs were even more so. However, it became a great surprise when Old Patriarch Song not only acknowledged Song Yu Han's identity and registered him into the Song family's family registry, but he also brought him to countless important gatherings.
