Mysterious man Li Jianjun, posing as a security guard, is assigned as the homeroom teacher to a problematic class and is immediately met with violent provocation from Zhang Cun, the son of the richest man. Facing the entire class's expulsion and threats, Li Jianjun remains unfazed. With a single sentence—revealing the secret that Zhang Cun's father owes him a 300,000 Swiss bank promissory note—he instantly shatters Zhang Cun's arrogance. Faced with absolute strength and an information gap, the unruly rich kids are completely subdued and are forced to obey the rules and start attending class, laying the groundwork for Li Jianjun's mysterious identity and the upcoming plot.
