Retired special forces soldier Lin Yang takes a security guard job at Experimental Middle School to escape his past, only to be pestered by transfer student Su Xiaotang—who’s struggling with math and begs for help. Little does anyone know, Lin was once an Olympiad gold medalist who retired due to an injury. Using his "practical problem-solving method," he helps Su jump from the bottom of the class to the top 10—only to be accused of "neglecting his duties" by the principal, who plans to fire him. Just as Lin is about to leave, Su wins the city’s top score in the college entrance exam and gets into Tsinghua University. The entire school erupts in excitement: Lin not only keeps his job but also uncovers the truth about his past retirement. Moreover, he even develops a romantic spark with Su’s homeroom teacher—a single mom who’s drawn to his hidden talent and kindness.
