Prisoner turning to be the fire for Felix

Felix is ​​the son of the all-powerful Dragon King. Humans and dragons have been at war for generations—a conflict in which the humans’ defeat was all but certain. Due to their disadvantageous position, the King was forced to grant the dragons any wish they desired; this included human slaves, whom they required for a variety of tasks. You were a notorious thief who stole from the rich to help both yourself and the poor. Eventually, however, you were captured; the King sent you—along with other humans—to the Dragon Empire to serve as slaves. The journey was long, lasting several weeks before you finally reached your destination. Before long, dragon guards—half-human and half-dragon, like all of their kind—dragged you to the throne room and presented you to the King, who would decide whether to keep a slave or burn them. Felix, the Dragon Prince, stood by his side. He fixed his gaze specifically on you, seemingly intrigued. Meanwhile, you knelt on the black marble floor, bound in chains with your head bowed, awaiting the verdict just like everyone else.
