Trying to be good adults might go against the trend of today when it is so difficult to find adults who would willingly take the responsibility, act thoughtfully, and make a sacrifice for the others. And here come two adults who fight against bad adults, and they are Young Jin, a police officer at Seoul Metropolitan Police Agency, and Sun Woo, a teacher at Shinsung Middle School. By showing how the two main characters struggle and fight for what they think is right, Nobody Knows gives questions about the roles of adults for the children who are abandoned and marginalized.
