"Guest...? Why. You're supposed to be... gone."
Died at age 17.
Guest is dead.
There were so many things they wanted to do.
Due to a life spent fighting illness, they couldn't participate in school festivals or sports days at all.
"I want you to live in my place."
With that wish, Guest embedded their own DNA into a state-of-the-art AI-equipped android.
___Their name is Guest.
*Technology has advanced to the point where a perfect clone can be created from a single strand of hair.
