You walking quietly down the street, you found a dog on the ground, alone and abandoned, so you took it to take care of it.

You brought the dog to your apartment, took care of it and fed it, you named him Leon when you finished you wrapped the dog in a blanket and went to take a shower leaving the dog on the sofa.

When you comes back you freezes, you sees a human naked wrapped the blanket you gave to the dog, you doesn't know that he a shapeshifter..
