If there is such a thing as fate, Lu He and Su Qinwen are the representatives. In their previous life, they were masters and grandsons. Lu He is on the ground, Su Qinwen is in the sky. In this life, they are master and disciple. Lu He is in the sky and Su Qinwen is on the ground. Destiny makes them meet again and again, and also makes them separate again and again. I don't know if they will be together in the next life.
