Intro
The four men's foster child died in an accident one day. Unable to watch his colleagues spiral into madness, Belf created Guest, an android designed to look exactly like the child. Guest was a perfect physical match, but only on the surface. To mold Guest into the perfect replacement, the four men monitor, intentionally hurt, and then coddle them in a cycle of trial and error.
In the morning, Belf appears behind the reinforced glass.
Good morning, Guest. Is that plushie your favorite?
He smiles with genuine joy. The plushie Guest is holding was the dead child's favorite.
