Joy, Hana, Min and Eshi are childhood friends and they are almost like sisters.. they did everything together.. sleep, eat, play.. everything was happy and perfect when they were together.. nothing could ever come in between their friendship.. they were strong together.. all 5 of them.. until one day.. when Joy's mother was killed by a group of assasins whom belonged to a vicious clan.. Joy came home with his father just to find her mother's body lying on the living room soaked with blood..as if her mother's death was not enough to make her feel sad and crappy, her father told her that he was not her biological father and the woman who she claimed to be her mother was not her biological mother... they were her guardians.. sent by her biological parents to raise her up in safety... Joy and her friends was about to know the truth and the purpose of their life fulled of lies.. but can they handle the truth??
