A tour guide in charge of running mini tours in Jeju Island. Her father is a gambling addict, but despite all the debts that he runs up, Yoo-rin always finds a way to help repay them. She leads a below-average life but is happy as long as she has her father with her. Because of her father's gambling ways, she has had to move from country to country whenever her father runs from one place to another to avoid their debtors. This has in turn brought her the ability to converse fluently in Chinese and Japanese, which are of great help as a tour guide whenever she has to entertain tourists from China and Japan.
