Love and Ambition (1987)

Park Tae-joon is an intelligent law student and a filial son to his parents who run a mill. He has a younger brother, Tae-soo, who is not quite as academic, but still quite smart and a known brat in town, and a younger sister, the kind and gentle-hearted Sun-hee. Kim Mi-ja, Tae-Joon's love interest, is from the same town and is sick and tired of living in poverty. She desires to leave their small town for a better life. One day after their father's death, the family learns that they will lose their home as a pledge due to an assurance their father has made before his death.
