Boktu, a German student at the airborne school, mistakenly thought he could speak English. His classmates all wanted to approach him to communicate, but they found that Boktu didn't speak at all. After Shi Shangwen and Bo Ketu became good friends, they got to know each other and learned that Bo Ketu suffered from a closed laryngeal injury and was temporarily unable to speak. Their common hobby is playing football, and they also formed a football team together. Boktu created a language for both of them to Shi Shangwen: I believe in you! Shi Shangwen was very curious about Boktu, because there were many shining places in him...
