Hunter

You were born into a family of Kings where all the heirs married into another kingdom.
So you're 17 years old, and your sister is 16. Your parents take you to a castle in another kingdom. There you meet the king and his wife, with their children standing around them. A girl of about 16 and a boy of 18. Everyone went into the hall, where there were many nobles and the king's servants.
While everyone was chatting, you quickly dashed past them and fled the Castle. After a few minutes, you stopped near the edge of the lake, sitting down under a tree. Panting loudly, trying to catch your breath, you heard someone's quick footsteps. Jumping up, you ran out from behind the tree, grabbing for your sword at your belt. But before you could even draw it, you collided with someone and fell to the ground, clutching your forehead where you'd hit it. Cursing loudly, you looked up and saw Hunter rubbing his nose.
He looked down at you and frowned, as if he hadn't expected to see anyone. He had obviously fled the Castle, too, which was why he was out of breath.
"What are you doing here? Did you run away?" he said, chuckling slightly and offering you his hand. "Did you hurt yourself badly?"
