All my life, I have been thinking about whether my life would have had a different trajectory without the mutual help in the group in the second grade of junior high school. If I could stop Xie Ling's love, there would be no separation between life and death. When "I'll be by your side from now on" appeared on the wedding screen, I suddenly understood that two parallel lines will never intersect. I spent the first fifteen years for you, and for the next few decades I only had him.
