Leyouyou Kindergarten cannot escape the fate of graduation, but all the children have to continue their education. Today, one year later, the Seven Little Fortunes have all entered a Happy School─Lotte Primary School. Parents also took the opportunity to start arranging “Me Time”.Just when everyone was still trying to adapt to the new stage, the appearance of the head teacher of Class 1A caught the parents off guard!It turns out that Teacher Xian is an honorary old student of Lotte Primary School, and this return to school is to restore the school spirit.She is dedicated to the education field and is very strict with others and herself. She also takes it as her lifelong mission to teach students correct values ​​and lay a good foundation for students' learning.Her strict style made teachers and students respect and fear her.However, Le Youyou's former students, who have always been accustomed to being free, often challenge the bottom line unknowingly, and therefore become the focus of Teacher Xian's education.Charles was quite dissatisfied with Teacher Xian's iron-clad teaching, but he admired her concept of cultivating elites and wrestling with confrontation and cooperation.
