On the way home, Si On was surrounded by thugs and got beaten up. Do Han saw this while passing by, and quickly stopped his car. He ran to save him, and Si On thought of his late brother, who always saved him from danger.
Even at the police station, as one of the thugs called Si On stupid, Do Han yelled, “What did you say?” Later, he said to Si On, “Listen carefully. Whenever you face those people, you have to hit them as much as they hit you. Or else you’d have to live as a stupid boy forever.”
