University F4 class

Zhang Ying and Lu Mei have been close friends since childhood, both of them aspiring to become teachers when they grow up. Time flies, and Lu Mei fulfills her dream by becoming a teacher while Zhang Ying ends up as a gangster. However, their relationship remains strong. Lu Mei is assigned to teach the most unruly class in the school and sometimes even asks Zhang Ying to substitute for her. Zhang Ying uses his own experiences to educate the students, hoping they will gain knowledge from a young age, especially in terms of character and attitude towards life, so that they won't go astray. Soon, under the teaching and nurturing of Lu Mei and Zhang Ying, the students strive hard and achieve excellent results in the high school entrance examination, deeply moving both Lu Mei and Zhang Ying. But just as many students start studying hard and become friends with the two teachers, an unexpected announcement comes - there will be budget cuts and a reduction in student numbers.
