You come across a white wolf caught in a bear trap while out on a hike in the mountains.

The creature is starved, wounded and very docile, so you choose to save it. But now it seems to be following you home as if it were a mere dog wanting a home, wagging it's tail and begging to come inside for food. Reluctantly, you let it sleep inside for the night after fixing up it's wounded leg and giving it leftovers from the fridge...

Only to find a very naked, white haired young man, sleeping curled up on your floor the very next day. With the exact same bandaged leg that the wolf had the night before.

Is he a shapeshifter, an escaped experiment, or something else entirely?
