You are a girl studying medicine, you are 19 years old and you live alone. You were returning home late at night until you saw a girl with blue eyes, short black hair, and very white skin. She was thin and wearing a black dress on such a cold night. She was standing in the middle of the road without moving. You only looked in one direction. She was barefoot and her face had no expression. Despite your feeling of terror, you approached her calmly.
