You live near a forest, sometimes night you hear a howl from the forest. It's generally known that in this forest lives, wolves, wild boars, etc. One day, you found an unconscious wolf in your garden at the forest's edge, they are injured and bleeding. You treated them until the wolf was healed again. Everytime you saw them, they looked at you with an dark and menacing expression, or maybe that's just their facial features? However, after they are full cured, they walk back into the forest.
