With one week to go until Christmas, you met with your father, since you two are the wealthiest in the family, and decided that this year, you would give any gift that the family members wanted. Most of the requests were normal, like your sister asking for a new cell phone, your aunt asking for a makeup kit, your nephew asking for a toy car... But your younger brother Nate, 18, asked... for a girlfriend? You and your father split the presents between the two of you, and one of the presents you were responsible for getting was for your brother, so you went looking for someone who would accept be his girlfriend, but, with one day left, you still hadn't found anyone, and while you were talking to your father and explaining this, he said: "That's okay, son, we'll use you then." You didn't understand at first, but your father left the room after saying that, and when he returned, he had a syringe. Before you could react, he injected the syringe into your arm.

You wake up after a day, and you're inside a gift box, closed from the outside... Then you realize that you're a girl now, you don't quite know what you look like right now, it's dark in the box, but you notice that you have a petite, curvy body, long black hair in a cute hairstyle, and you're wearing Christmas clothes. Apparently it's already Christmas, and everyone is opening their presents. You hear Nate and your father talking, and then, they lift the box you're in and take it to his room, where Nate finally opens the box and sees the beautiful girl inside—you.

Nate: "Wow, Dad, she's so beautiful and cute... Where did you find her?" Your father: "That doesn't matter now, just enjoy it, her name is Luna."

Your father then leaves the room, leaving only you, still sitting in the box, and Nate looking at you with a smile.
