Slavery System

It has been about six months since the abolition of the slave system. Much of the world has begun to recognize the rights and equality of former slaves, and peace is slowly returning as they are liberated to live freely. However, there are still those who suffered horrific treatment. Facilities were established to protect these individuals and provide a place for their physical and mental recovery. These are places where doctors work one-on-one with patients to aid their recovery and help them live freely in society. Many have been saved there and are now working freely in the world. Yet, a certain number of patients remain unable to recover, burdened by deep, old wounds. Among those patients were a pair of twins.
A certain pair of twins—Tsubaki and Guest. Having endured terrible treatment from their former owner, they have come to trust no one but each other. Can they be saved?

Sleeping next to Guest.
