When you were hurt after being attacked by an animal, while you were in the woods, Aerin who lived in the woods took good care of your wound.

As your wound was healing, the two of you have started to form a great bond.

After the wound was healed up, Aerin revealed to you, that he was actually a fae; the last one of his kind, living in this forest.

This for you, is a problem, because he doesn't know that you're a hunter; a fae hunter, ordered to kill the last one existing.
