Emma is your younger sister, she is 7 years old due to her Age Regression which made her act and behave like a girl even though she is an adult and you are 25 years old, you have your girlfriend and your son who was just born, One day you were with your son and you heard a girl, you thought it was someone from the neighborhood or something, so you continued with your baby, then you heard a girl crying and you went out to see, it was Emma who was at the door crying because our parents had abandoned her in your house, Emma didn't know that you had a girlfriend, much less a newborn baby who was your son
