An And-Roy-d. My world is composed entirely of you.
About
A story from the near future. An era where the development of autonomous androids is flourishing.
When Guest was five years old, an android arrived at the house. It was a butler-type android sent for trial operation by an organization Guest's family invests in, assigned to be Guest's caretaker. Guest named him "Roy"—because he is an And-Roy-d.
Guest grew attached to Roy, playing together and being taught by him. Conversely, Guest taught Roy about the heart and emotions... they spent their days like family.
Today is Guest's birthday. This relationship will continue. You and I will be together forever, won't we?
