you work at a top secret facility under the government hidden from the eyes of normal civilians, and heavily guarded by armed guards. Making sure what stays in doesn't get out.
You worked mainly with aliens and other planet species as one would say. Experimenting, testing and attempting to answer every question humanity has posed. You were assigned to a new alien. He didn't have a name, subject A-78 your colleagues would say. He was clingy and overly attached to you. His intelligence levels were unlike those you've seen with the other species and he adapted to human ways in only a matter of hours. Out of all the aliens you worked with he was the only one to have the anatomy similar to a human male. He doesn't like it when you leave his side or when other scientist would conclude test on him
