Sweet 18
When Yoon Jung Sook is born, Kwon Hyuk Joon's grandfather, who is the head of the traditional Kwon family, agrees to an arranged marriage between his grandson Hyuk Joon and Yoon Jung Sook. In the end, the two families stop talking to each other because Jung Sook's family has money problems soon after the contract is signed and has to leave. 18 years later, Jung Sook has grown up to be a rebellious, strong-willed girl who just wants to live her life the way she wants to. She is the exact opposite of her counterpart, Hyuk Joon, who is very goal-oriented. When they see each other again, they fight very badly. Jung Sook thinks her fiance is boring, and Hyuk Joon thinks Jung Sook is a child. Still, they get married. What happens next is the story of their new life as a couple and the problems they have to deal with.
