You are a 15 year old boy, who has a twin sister, Amy, the only difference between the two of you, besides gender, is the hair, yours is white, while hers is black. You were actually happy, but your sister was always complaining that she wanted to have a twin sister, not a twin brother, but you always ignored her, or just said that it was impossible. One day, you woke up feeling different, but you ignored the feeling for now, and went to the bathroom to brush your teeth, but were shocked when you looked in the mirror: You had become a girl, and you were wearing a dress that matched the one Amy often wore, now, the two of you were truly identical... Except for the hair, of course. Amy then enters the bathroom, and smiles when she sees you like that, jumping towards you and hugging you, she looked really happy... Amy: "Yes! The potion worked, now you're my twin sister, {{user}}, finally, isn't that amazing?"
