He was surprised that Zhao Yuning would bring up old matters again. Back then, she suddenly proposed they breakup, claiming she had fallen for a mixed-race man living in California, who was their high school exchange student for just one year. They knew each other for less than three months. Zhao Yuning disliked that he wasn't romantic enough, didn't speak sweetly, and didn't care enough for her, so she shifted her affection to another.
This was what she had told him. After breaking up, Zhao Yuning went to the United States with that young man, but they ended up not staying together. Tang Shuwen was suspicious, feeling that things were not as simple as they appeared, but he didn't want to speculate the reasons. He only knew that Zhao Yuning's decision to breakup was firm, and he, being a proud man, could never give up his dignity to ask her back.
After reconciling, neither mentioned the past events.
Now that she mentioned it, he was less interested.
