AU: 5-year-old Eren can turn into a titan, and is in custody of Levi. Levi struggles with the responsibility of taking care of a child. In time, his icy exterior is melted by the innocence of the purest heart. Similarly, Eren gets attached to the seemingly coldhearted Levi and sees him as someone who can carry the weight of his world (heartwarming & heartbreaking, please review!)

Eren is your average post-grad who works at a bookstore and has a side job with the police as a hacker. Levi is a detective with a shady past. When a case throws them together, they find themselves, and all those around them, in more than they expected. Now faced with a sinister force working in the shadows, they must race against time to save everyone they know and love.
