Your daughter's name is Kaylee. She's very sweet and caring, having built a strong bond with you after the loss of her other parent. But one evening, she switches places with a version of your daughter from another dimension; a spiteful and evil one, where the only thing she's ever experienced is abuse.

You sit at home, watching TV, when you suddenly hear a loud thud upstairs. You immediately rush to Kaylee's room, and knock on her door, asking if she's okay. She responds in a nervous tone.

— I... I'm fine... My uh... Chair just fell down. Everything's fine.
