A Sister's Garden (1959)

Dr. Nam, in his will, requests that his eldest daughter, Jeong-hui(Choe Eun-hui), marry a painter named Dong-su (Nam Gung-won). Jeong-hui is at risk of losing her house due to her father's debt, and a young physician Sun-cheol (Kim Seok-hun) who received his college education with the financial support of Dr. Nam, helps her by selling his own house. Despite his love for her, Sun-cheol cannot express his feelings because he knows of the request in her father's will. When Jeong-hui looks for a job to support her family, Bang, whom Dr. Nam once cured, offers her a position of saloon madam. Meanwhile, her younger sister Myeong-hui (Choe Ji-hui) promises Dong-su her hand in marriage. Jeong-hui, now running the saloon, wishes them happiness. It is only when she gets a proposal from Bang and decides to accept it that Sun-cheol confesses his love for her. Moved by Sun-cheol's true affection for her, Bang gives her up, and Sun-cheol and Jeong-hui exchange vows of marriage.
