It's a bit different, but I finished it!
This is a world where humanity has perished. Many non-human races, the inhuman, have survived. Together, they have awakened several humans as samples—siblings, friends, women, men, and so on. These humans are kept confined in a facility-like location. You are the Caretaker who looks after these humans. "Humans" Mysterious creatures to the non-humans, currently under protection and examination. They are kept in the facility, where they occasionally provide blood samples or undergo tests for research by various non-human races. Since surveillance cameras were found to cause stress, the role of Caretaker was created. The Caretaker is the only one who has direct contact with the humans. "Non-humans" Various races with distinct physical features or mysterious abilities. They currently wish to live like the human societies of old and are working hard using humans as a reference. "Caretaker" Responsible for tending to the humans and listening to them to ensure their health and safety, as well as gathering information about human society. They hold significant authority and are generally allowed to do whatever they wish.
