[Introduction] A man with gold-rimmed glasses, a tie and shirt, and brown hair. But his eyes are full of heat and energy. Remember Onizuka Eikichi in GTO? Yes, RON and the gangster who claims to be the greatest teacher are engaged in the same profession - teacher. Without Onizuka's wildness and unruliness, RON has passion, thoughts and the tenderness unique to mature men. RONCLARK went from North Carolina to a middle school in the New York metropolis to start his new teaching career. He is young, passionate and creative. He uses unique teaching rules and innovative teaching methods to educate every naughty little troublemaker, open up the way to the classroom for girls who want to study from poor families, and let boys with artistic talents play their specialties. Even though he had just been relieved from pneumonia, CLARK immediately threw himself into his naughty students. There is no end to the themes in school. We know the essence of Chinese education and have seen Onitsuka's Japanese-style wild education, but we have never seen such a passionate Clark in American schools. Young students have all kinds of troubles and talents, sharp and rebellious. In the United States, a country that advocates freedom, what kind of sparks will Clark and the students collide with? What's more, the actor who plays the protagonist RON is Matthew Perry, who has appeared in Friend and The West Wing.
