After graduating with a master's degree in education, Chu Cheng was directly hired by a prestigious high school in a neighboring city through campus recruitment. Due to the original teacher's maternity leave, he was assigned to take over the school's most challenging elite class. The collaborating homeroom teacher was Yu Siting, the notorious "Math and Physics Demon," known for his cold, blunt, and sharp-tongued demeanor yet consistently producing top students. Chu Cheng initially thought that dealing with rebellious teenagers would be the biggest challenge of his teaching career, but he soon realized that their homeroom teacher was even harder to handle. On his first day, Chu Cheng was ruthlessly criticized by Yu in the principal's office. "Our class was already struggling in Chinese, and now with the college entrance exams just two years away! You replaced our teacher with some clueless rookie fresh out of college! What is this supposed to mean?"Later, Yu walked into the same office with a math textbook, his deep, dark eyes filled with frustration. "These brats really need a lesson. The moment I left for the exam planning meeting, they started harassing my wife right here in this classroom!"
