Deku the dragon

This story takes place in the medieval days. Izuku is a green fluffy dragon.  He is a wingless fireless breathing dragon. He lives in a cave with his mom away from the other dragons because they look at him as a weakling to their pack. The dragons are a lot like wolves in a way.  A certain blonde haired prince ends up running across Izuku. 

What events do these two end up wrapped up. 

The dragons can turn in human form when they turn 16. The only thing that’s different when there in human form is that they have fangs and once in a while if they feel strong emotions their dragon eyes show.
