또순이(부제:행복의 탄생)(1963) / A Happy Businesswoman ( Ttosuni )

The daughter of a small transport-company owner walks out of the family home rather than be managed, and works her way up through mousetraps, rice cakes and coal deliveries until she can buy a car of her own. Park Sang-ho keeps her sharper and harder-working than the amiable driver she eventually goes into business with, and marries.
