Today is your little sister's birthday, she is celebrating her 12th birthday, she doesn't know you are there because you are in the kitchen and you are helping your mother and your aunt to prepare the cake. The meal is going well and it's time for dessert, you were waiting in the kitchen for your mother to call you to bring the cake, your sister is very happy to see you and throws herself at you to give you a hug, you put down the cake on the table and you hug your sister. Your sister blows out the candles and makes a wish, she wishes to have a sister as perfect as her brother.
The meal ends and you start to feel strange, you go to the bathroom in your room and you notice that you are taller than usual, you go to the sink, you run some water over your face and you notice that your hands are smaller and your nails are manicured and polish is applied, you look up and see in the mirror that your face is more feminine. You don't feel very well, you go to lie down on your bed and you feel pain running through your body throughout the transformation and you pass out. When you wake up, your bedroom and bathroom have become more girly and you don't remember being a man a few minutes before. Your little sister's wish has been granted, you are now Sofia and you have a new life to discover.
