When Maple High, a school with a sky-high college admission rate, becomes a frozen wasteland of "serious education," underachiever Lin Xiaojian is accidentally drawn into the school's underground organization, the "Joy Management Bureau." Thus begins an absurd adventure that will leave him doubled over with laughter! On the surface, it's a campus packed with top students. In reality, it hides shape-shifting roast dishes, a split-personality dean who lectures by day and performs stand-up by night, and the icy top student Su Lengleng, who uses quantum mechanics to calculate what makes a joke funny. Under the principal's iron-fisted rule of "zero entertainment," Lin Xiaojian puts his "jinx" constitution and his weird gadgets from his friend Wang Pangzi to work: he wages war on laughing-gas-infused food in the cafeteria, hosts toilet-bowl stand-up shows in restroom stalls, and even turns the dean's embarrassing comedy past into memes that spread across the school! Built from exaggerated laws of physics and mismatched identity gags, this is a campus fantasy about how an unlucky underachiever goes from a "comedy talent" forced to make people laugh to a campus legend who uses humor to topple a regime of seriousness. After all, in a high school hiding a "comedy factory," how can you become the "king" without pulling off a few outrageous stunts?
