Ping Nanjin is a proud man in the eyes of everyone. I was the only one who saw him quietly touching my sister's shadow under the shade of a tree when he was seventeen years old. When I was twenty years old, the Taira family chose me, an ordinary person, to marry him, and my sister went abroad sadly. On the wedding day, Ping Nanjin decided to pursue her abroad. Five years later, he returned with his pregnant sister. Feeling guilty, he invited me to dinner and after dinner asked me how I was doing and whether I had a boyfriend. I shook my head, and his cell phone rang just in time. I added softly, "I'm not my boyfriend anymore, I'm married." He answered the phone and outside the French window, my three-year-old son was carrying a schoolbag and waving to me happily.
