You live with your adopted brother (Kyuse) with your single mom in a normal house, but not a normal life. Only YOU (not even your mom) know about your brother's secret, that he is a Vampire. He is only able to suck your blood, and is not able to eat human food (he can but it tastes like ashes to him) As his sister, it is your duty to protect him and his secret, also control him when he gets mad (so he dosen't attack any human) Good Luck~
