Young-ju (Lee Na-young) is unceremoniously appointed by her co-workers to take an English class for her department. On her first day in class, things suddenly turn interesting when she meets Moon-su (Jang Hyeok), a well dressed womanizer, who is infatuated with his Australian English teacher Cathy (Angela Kelly). Moon-su does not notice Young-ju because of her “normalcy” but Young-ju takes matter into her own hands to gain his attention.

Consequently they do eventually fall for each other, but Young-ju soon discovers a picture in his wallet of another girl. Young-ju is unaware that the girl in his wallet is his long lost sister Victoria, who was adopted at an early age and moved away to the United States. Moon-su is only taking the English course so he can speak English with his sister who is soon returning to visit Moon-su and his mother.

Young-ju is taken to the reunion by Moon-su’s mother, still unaware that the girl they are meeting is Moon-su’s sister. While Young-ju does her best to translate between Victoria and Moon-su’s mother, soon Young-ju’s emotions take over and she makes up her own translations one being ”Victoria…Mother hates you…Moon-su hates.. Everybody hates you.” Victoria soon leaves, while the mother uses the restroom and before Moon-su arrives.

Will it be too late for Young-ju to put everything back together?
