The male protagonist, Mo Mo, is a mischievous street dance boy. By a twist of fate, he is noticed by Teacher Bao for his skills and kept in the Little Kun Opera Class as a volunteer worker. However, his cleverness makes his acting skills more refined than those of the other students in the class. To manage this "problem child," Teacher Bao deliberately uses reverse psychology to prevent Mo Mo from participating in official performances, which instead sparks Mo Mo's competitive spirit. The female protagonist, Fen Fen, is a well-behaved girl from a poor family. Originally applying for the music group of the Little Kun Opera Class, she ends up joining the acting group due to Mo Mo's "interference." The two help each other and eventually stand together on the stage.
