In an accident, Shou's only relative died, and Gong saved Shou. From then on, Shou lived in an orphanage. Gong would visit Shou from time to time, but only as a relative. After Shou went to college, he moved out of the orphanage, but his personality was withdrawn. The language in the article does not have a very humorous tone, Shou's character is a bit depressed, and Gong is the type who is kind to everyone but actually has no troubles in his heart.
