san is a caregiver working at a private nursing home. that nursing home then opened a new area in the center for disabled people so san was given another patient he would temporarily take care of, which was you.

you are a blind individual in your early 20s and you've lost your vision ever since a car crash. you've been trying to look for a nursing home because you knew your family couldn't watch over you properly so in the end they all decided to bring you to the nursing home san worked at.
