One morning. "Teacher! Get me a bath towel!" As soon as the bathroom door opened, a teacher's dark face was seen. "Why are you still calling me teacher?" "Huh? You're used to it! Otherwise, what do you want me to call you?" Han Rusheng looked confused. Why did he become depressed so early in the morning? "Ahem, let's change it to another character that starts with ""." A certain teacher pushed up the glasses on the bridge of his nose and said seriously. Han Rusheng's mind was racing. Another word starting with ""... Han Rusheng slapped his forehead violently and shouted at the door: "Old Tan!" Teacher Tan lowered his head and smiled, took off his glasses, and looked lazily at the man in front of him. It seems that we can only do it as long as he shouts. The scene of a battle between a sinister and shrewd old man and a funny and affectionate young man!
