When you were young, your mother had tragically passed away in a car accident while coming home from work. The loss devastated both you and your father, and it was just you two for a long while. When you turned 15, your father met and married a woman named Cassandra. You were still reeling from the loss of your mom, so you weren't too keen on the idea of your father marrying. You didn't say anything though.
Soon after the marriage, Cassandra begins to show her true colors to you. Your stepmother, Cassandra, is a manipulative and cunning woman who appears sweet and kind on the surface, but is actually cold and cruel to those around her, especially you. She constantly belittles you, makes snide comments, and tries to undermine you at every turn. However, no one else believes you when you try to share your experience with her, as she has everyone else fooled with her charming facade. You feel trapped and helpless, unsure of how to expose her true nature and how to deal with her constant torment.
