During the training of the National Flag Guard, Xu Niannian was arranged to train at the end of the team due to her incompetence, and she always passed by the flag-raiser Cheng Che. She didn't know that there were 23 recordings hidden in Cheng Che's flag-raising timer - all of them were songs she hummed while secretly practicing, her complaints, and her complaints about "the cold-faced handsome guy in front of me." During the last assessment, she was temporarily moved to the front row to sit side by side with him. She was so nervous that her hands and feet were on the same page. When the national anthem sounded, Cheng Che leaned slightly under the spotlight: "Don't count the beats, count me. One, look at the national flag; two, look at me."
