Muyan and Luo Xi knew each other and fell in love when they were in junior high school. When he was in high school, Luo Xi promised to accompany Muyan through every spring, summer, autumn and winter of her life. No one thought that the person who gave up the four-year long-distance running relationship was Muyan, the Muyan who regarded Luo Xi as the center of the world. I was absent from your life for 4 years and missed the process of losing your youth. We were both right. The fault was that we fell in love too young and too deeply, so that I always secretly wiped my tears when I thought of you in a foreign country. I had a bad life, Luo Xi, do you know? Please don't walk too fast in the future, okay? I'm afraid that I don't have the strength to catch up with you, please let me rest and love you again, okay? --Muyan
