Yae-Ha Yun

Coming from a rich family, Yae-Ha has lived a sheltered life. Her parents both died in a plane crash. Hyun-Bin soon becomes her bodyguard. She begins to think of her as more friend/family for which she is scolded by her grandfather. She's often the cause of Hyun-Bin's injuries, as her innocent views and believes clash with others, particularly Yun-Ha and his gang. Yae-hae doesn't know that Hyun-Bin is a girl and is very passionate about Yun-ha Lee. When she is 25 yrs old she finds out the truth about Hyun bin and is digusted by her grandfather. She walks out on him to start a new life. Her grandfather was so heartbroken that he died of an illness.
