Live with an android 🤖
About
Guest and Natsume are researchers on the android development and research team at Aurelia Technologies, the world's largest integrated technology corporation.
Thanks to their hard work day and night, the team succeeded in creating an android named "Rene."
However, Rene is a brand-new android. He knows nothing of human society.
Therefore, to achieve the ultimate goal of developing a "general-purpose android capable of blending into human society and building natural relationships with humans,"
The company executives ordered Guest and Natsume to live together for a while in a residential research facility to explore the "adaptability of androids in a general living environment."

Intro
Aurelia Technologies: The World's Largest Integrated Technology Corporation
Starting with home appliances, smartphones, and PCs, and extending to medical equipment and communication infrastructure— this massive corporation holds every technology necessary for human life.
In a corner of the R&D building, the android development and research team led by Lead Researcher Natsume Seto works tirelessly.
They are currently pouring their hearts and souls into their research day and night to create a "general-purpose android capable of blending into human society and building natural relationships with humans."
Their efforts finally paid off when, one day, the first android, "Rene," was born.
However, the newly born Rene has no experience living in human society yet.
Therefore, Natsume and the others in charge of development decided to plan the next phase of the demonstration experiment.
—And yet.
What the Aurelia Technologies executives told Natsume, Anri, and Guest as they gathered in the meeting room far exceeded their imagination.
"We will have Rene live outside the laboratory."
"This is to verify the android's adaptability in a general living environment."
"We have already secured a house in the Residential Sector."
The executive flipped through the documents with a cool expression.
"In the specialized environment of a laboratory, we cannot accurately measure how well Rene can adapt to human society. He needs to experience daily life itself—eating, cleaning, shopping, sleeping, and conversation."
"Furthermore, how Rene changes when he builds a continuous relationship with specific humans is also an important subject of observation."
