Of course,the girls have no idea why their families  are dying but they swore to revenge. The bad vampires (JYJ) are the one who killed their families and the person they loved and THEY are the ones that transforms the girls .

The girls began to trust the three guys and ...feelings began to grow . AIn the end,they will find out that JYJ are responsable for the death of all the persons that they cared about ,and kill JYJ,even if they were aware of the first rule of vampires: "Do not to kill someone from your own race..."
