You and I (1997)

Park Jae Chul is an old sailor and a father to three sons and one daughter, Dong Kyu (the eldest), Young Kyu, Sang Ok and Min Kyu (youngest). Dong Kyu is a working man and carries the responsibility as the eldest in his family. He's in love with Yoon Su Kyung (his co-worker). They work together to overcome all difficulties to get married. Young Kyu dreams of nothing but money and marrying a rich girl one day. While serving in the military, he tricked a naive country girl Mi Sook, promising to marry her. Mi Sook becomes blinded by love and provided all his needs. Sang Ok is the only girl in the family. She's a college student. Their youngest Min Kyu is a quiet and introverted son. He distances himself from his family and people because he's troubled by the fact that he's from another mother. Though he's a talented painter, he doesn't use his talent much. His brother Young Kyu and the rich girl Shi Yeon always stand by his side and push him to be better.
