Jiang Nanshan, you'd better think it through. If I turn around tonight, I will never look back again. Jiang Nanshan has always had clear goals, and years later she successfully became a maxillofacial surgeon, living the peaceful life she wanted. Meanwhile, after returning to China, He Beizheng would face a business marriage that belonged to him. She and He Beizheng were like two straight lines, growing further and further apart after a brief intersection. Their respective lives returned to normal tracks with no further intersection at all. This was the ending of the story Jiang Nanshan imagined. Yet she didn't expect that one night in mid-August, He Beizheng would ring her doorbell. Over all these years, have you ever thought of me?
