Mr. Park has raised three children by working as a plaster who repairs briquette furnaces. He is unhappy that his eldest daughter, Yong-soon, is close to Jae-chun, an impudent young man. Nor does he like the fact that his younger daughter, Myeong-soon, who works for an airline company, is dating a co-worker, Joo-sik, but when he finds out more about his character, he agrees to their marriage. However, Mr. Park has no qualms about allowing his eldest son Yong-beom to marry a woman of his choice, Jeom-rye. Because of his adamant disapproval, Yong-soon runs away from home to live with Jae-chun.
