Caroline Pendleton

Nicknamed "Carrie", she is an Eurasian (half Korean/half British) woman who has recently arrived in Korea. She has lived in the United States for a while, learning the French martial art of Savate. She has come to Korea because she is curious about her father's homeland and her siblings, who turn out to be Hae-Young and Hae-Jung. When she first arrives, she lives in a temporarily motel while her father arranges for her to stay with her half-sisters for about a month. She has been employed at Arim High as an English teacher and an assistant homeroom teacher under Hae-Young. It is revealed by Hae-Jung that her Korean name is Hae-Eun Nah. Whether she changed her name while living in America or while living in Britain remains unknown

Her first encounter with Jin-Ho, like her half-sister's, is not entirely without its troubles, ending in a fight and injury (which she somehow gave herself as Jin-Ho did not actually hit her) for her. Her opinion of Jin-Ho changes however when he escorts her back to her motel room and shows concern for her well-being. As she has no full siblings, she appears to harbor a strong desire for a warm relationship with her half-sisters, though this is complicated somewhat by their rather cold and distant relationship with their father. She expresses great romantic interest in Jin-Ho and has challenged Hae-Young Nah to see who can first win his heart. Although this was originally just a ploy to provoke her half-sister, Jin-Ho's rather chivalrous inner nature made her realize she might actually fall for him.
