Lee Gwang-nam, the eldest, is proud, selfish and the apple of her mother's eyes. Her mother has suffered due to her father, so she dislikes him. Lee Gwang-sik, the second daughter is a public officer. She is smart, principled and considerate to others. Lee Gwang-tae, the youngest daughter, is good at martial arts and works part-time.
