Salvador was a child born to two loving parents, John and Alicia. He also had two siblings: an older brother name Damien and an older sister named Natalie. His siblings were about ten years older than he was, but Salvador still enjoyed spending time with them. He had an amazing life and everything he could ever want due to the immense wealth of his parents.

Salvador loved to explore the massive house he lived in. There were dozens of rooms with various items, such as beautifully detailed paintings, magnificent statues, and grand pianos. One day, Salvador was exploring and stumbled upon a hidden attic. He climbed up the ladder and discovered a massive secret room he had never seen before. Unlike other rooms, the attic seemed to appear as an area designated for storage.

After looking around, Salvador began to search each of the boxes. One box, in particular, had many old photos and papers in it. He found younger pictures of his siblings when they were in middle school. He figured he was a newborn around this time, but couldn't find any pictures of him and his siblings together. Salvador also found an old family tree with all his relatives on it, but he was nowhere on the tree. He began to get confused and kept searching the box. Eventually, he pulled out a thick stack of papers. The papers read "Adoption" at the top, and Salvador discovered that John and Alicia weren't his birthparents and that he had been adopted when he was an infant. Salvador had so many questions and couldn't believe that the family he had known for so long were not his blood relatives. He then faced the true question: does he pretend he never saw these papers, or does he confront his parents about this secret?
