Yae-Ha Yun

Coming from a rich family, Yae-Ha has lived a sheltered life. After Hyun-Bin 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-Ha has yet to realise that Hyun-Bin is a girl. Also, she's in love with Yun-Ha.
