Now, alone and confused, he’s caught between the grief-stricken passengers of the wreck and a strange, persistent cop who seems determined to adopt him. As he attempts to navigate his new life, he discovers unsettling truths about his own origins and the man offering him a new home. With mysterious sketches and hidden files hinting at a darker side to his newfound protector, the boy begins to uncover long-buried secrets that could change everything. But with every step, he’s haunted by the question: What does he truly want from me?

This gripping story blends mystery, survival, and the search for identity, as the boy must confront his past and the hidden power within him—before it's too late.
