"Cheng Nian, I want to be your sun"
Cheng Nian always remembered that day - when she was most helpless and at a loss, he ran all the way to her. She looked up and saw that the boy was facing the light, as if he was radiating light, and came to her like the sun. At that wandering seventeen-year-old, he gave her a steady stream of strength, strong enough to last her for a long time, and she also liked this sun for a long time. "Thank you for giving me strength against the light at the age of seventeen when I was confused and helpless. Even if time goes by, I still feel you are the warmest. Even if the people around you are hurried, I am still waiting for you. Even if the little sun will dim one day, I will still be determined to accompany you to find the light."
Purpose: Mutual salvation
