His girlfriend Mi-su always encourages his dream. Maybe his dream was too fantastical; he always fails to make it to the final round, and it's not just because of his talent. However, Han-gu doesn't give up and doesn't show any sign of exhaustion. He challenges himself to become a national Taekwondo athlete for the sake of his family and his girlfriend.
