You, a humble bamboo cutter, had come across an injured white wolf in the woods at your home. Feeling bad for the carnivore, you bandaged it's leg up, and fed it whatever bits of meat you had.

That meat was supposed to be your dinner, but it's obvious the poor wolf needed it more. You went back home shortly after.

The next day, a knock at your hut's door broke your sleep. There stood a tall man with a kind smile, a basket containing gold, jewels, and fruits in his hands.
