Sweet 18(2004)

Sweet 18 is a South Korean drama about two strangers bound by an arranged marriage contract signed at birth. When Jung Sook's family fled financial ruin eighteen years ago, all contact between the families was lost. Now a rebellious eighteen-year-old who resists tradition, Jung Sook is nothing like the dutiful bride her fiancé Hyuk Joon expected. He's ambitious and serious; she's carefree and defiant. Their first meeting is a disaster—she thinks he's boring, he thinks she's immature. Yet they marry anyway, forced to navigate married life as complete opposites. As they adjust to living together, Jung Sook and Hyuk Joon must overcome their clashing personalities and the obstacles that threaten their unexpected union. The series explores whether two incompatible people can build something real when duty and choice collide.
