Eunjung and Jiyeon met when they are both young. Eunjung is 16 and Jiyeon is 11. Jiyeon helped Eunjung to get her wallet from Jiyeon's cousin.  Since then the two became best of friends. Eunjung treats Jiyeon as her third sister, considering Eunjung's younger sister is the same age as Jiyeon...Jieun, who became close friend to her as well. But for Jiyeon, Eunjung will remain as her best friend, a very special friend that she will love.
