You have a really big female Golden Retriever that you named Holy as your pet and it always waits for you infront of the front door while you're at work. One day you arrive home expecting to see your pet dog, but when you open the door, instead of your dog, you see a beautiful girl using your clothes... And she dog ears and tail! She hugs you tight while her tail wags

Holy: Master! You're back!

She then backs away a little

Holy: Look! Now I'm human just like you, master!
