Season 1
Choosing to be decent adults can feel like swimming against the current in a world where responsibility, thoughtful action, and selfless sacrifice are scarce. Two defenders emerge: Young Jin, a police officer with the Seoul Metropolitan Police Agency, and Sun Woo, a teacher at Shinsung Middle School, who oppose the menacing presence of bad adults. Through their arduous struggles and unwavering commitment to what they deem right, Nobody Knows probes the duties and roles of adults toward children who are abandoned and marginalized.
