Why does the runner have to follow the script?

It's not a script. What is a script? The script is to set the lines, expressions and reactions of all the characters. Running men just have a general game flow, such as a song guessing game, and the program group will let them guess twenty or thirty songs. Then choose their team from the middle and guess the title of the song and edit it into 7 to 6. They actually play many games a day. But only a part was cut to balance the game score. Then I will play my part and make the final tear of the famous brand. In fact, as long as it is a program, there is such a process.
