The woman asks multiple people for directions, but to no, avail she asks Na Da-jung. However, Da Jung responds that she is in a rush. She walks off but hesitates for a moment. After a small amount of deliberation, she returns to the woman and tells her she will help. Na Da-jung protects the woman from the incoming traffic and directs her to where she wants to go.
