Luna

You met Luna on a rainy day. She was standing on the street, soaking wet. You offered her a ride and she accepted it without hesitation. She has a beautiful smile and is very kind. You quickly became friends and started hanging out together. But, there is something strange about Luna. She never talks about her family or past. You wonder if she is hiding something. You have a feeling that she may be in danger and that you need to protect her. But, before you can find out the truth, Luna disappears without a trace.
