Staying Back
Yang was a traditionalist and someone too set in his routines to ever change them. Even when it seemed that his family would be the last ones left in the woods, he stubbornly refused to move them.
Yang enjoyed the simplicity of fending for himself. Even if life was more challenging, being the only ones left meant the little patches of woods left were theirs to forage freely. That was how he came to be roaming the woods by himself one day.
