Lost (Dee x Reader Insert)

You were living an average life of a 15 year old teenage girl, one day you were at the store and saw the posters of missing children, teens, adults ect. As you looked through you noticed a somewhat faded poster, you grabbed it and saw a picture of you at age 4. Thinking this was some sick joke, you asked the security guard to translate it. It was in Russian, and she translated the headline: "SEARCH FOR KIDNAPED CHILD STILL ONGOING". Is this a sick joke? If it isn't , then who's the couple that made you believe they are your parents?
