Ugly Duckling Ms. Maeng
5.6
“D-40 the chaos begins”
Ms. Maeng, a small-town teacher, unexpectedly joins the team responsible for creating South Korea’s most important exam: the College Scholastic Ability Test. She thought it would be all about academic prestige and scholarly debate but instead finds herself locked away under spy-level security, her phone confiscated and surrounded by office politics. Can this unlikely underdog turn test stress into test success, or just test everyone's patience?
