Lin Xia and Chen Mo met while staying in Dali. After spending a long time together, they gradually became friends. Lin Xia was a first-year graduate student, while Chen Mo was a sophomore. Their schools were in the same city, and they made plans to go out together. By chance, Lin Xia learned how Chen Mo felt about her and realized that she had fallen for him too. The two got together. Later, Lin Xia’s advisor secured her an opportunity to study abroad in Country X. Chen Mo had just passed the cutoff for the second-round admissions exam at Lin Xia’s university and was preparing for it. When he learned that Lin Xia would be going abroad for a joint program, he wanted to give up the exam and apply to a university in Country X. Lin Xia thought he was being too immature and not taking his future seriously. Chen Mo believed this would give him a chance to keep studying alongside her, but Lin Xia disagreed, feeling that he wasn’t being responsible about their relationship. After they fell out, Lin Xia broke up with him so he could have a stable future. Four years later, after earning her PhD, Lin Xia was working in Country X when a work obligation brought her back to China. She gave a lecture at the university where Chen Mo was pursuing his doctorate, and the two met again. Lin Xia gave up her job in Country X and returned to her master’s university to take a position. She also started a business with classmates who had studied abroad with her and later returned to China. Through work, she often interacted with Chen Mo’s research group. They both came to understand each other’s perspective at the time, and got back together.
