Cursed (Victuuri AU)

Prompt: "You're a dragon that is cursed to changed into a human every night. One day a knight comes to slay you, and imagine their surprise when the dragon they're about to stab vanishes in a puff of smoke, leaving a defenceless human crouches in front of them." - @writing.prompt.s (IG)

Victuuri AU

After a gruelling hike through the mountains, the knight was more than shocked not to find a fearsome, malicious dragon but a boy not much younger than himself curled up with tear stains down his dirty cheeks in its stead.

The knight quietly took off his helmet and looked around the cave of the supposed "Killer Katsuki," a dragon that had been ravaging the nearby kingdoms for the past decade. However there was no dragon, only a boy chained up by the ankles to the wall of the spacious cave. Other than the boy in shackles, there wasn't very much in the cave. The boy was curled in on himself on his side next to a slow burning fire in the middle of the cave on what looked to be some blankets. On the other side of the fire, there lay a pile of wild berries and small fruits that grew in the forest at the foot of the mountain. In one corner there seemed to be a pile of worn fabrics and old clothes, in another corner there were a few animal bones which made the knight's breath hitch. He hastily took a few steps to investigate each corner and deemed there not to be any human remains, only what seemed to look like deer and rabbit bones. He sighed a small breath of relief before confusion set in.

Where was the infamous dragon he had come to slay? And whatever was a boy doing here surrounded by all of this on his own, let alone being chained up?
