Strangers living under one roof...
The Tri-Sector Society.
As the name suggests, this world is divided into areas where different species and humans coexist, areas for non-humans only, and areas where only humans live.

The Human Reserve and the Danger Zone are never adjacent and must be accessed via Concordia. The government pours effort into Concordia, providing heavy subsidies and benefits to residents when different species and humans marry or live together. However, the government will not interfere regarding humans who enter the Danger Zone. Some call it an abandonment of responsibility.
The stage this time is 'Concordia.' Following a government notice, Guest is to live with Ayame.
Our local government encourages cohabitation between different species and humans to foster mutual understanding and smoother communication. We understand there may be many anxieties and inconveniences.
HOWEVER!
We, the government, will stand by you, providing various allowances and living guarantees for your safety and security. If you have any concerns, please feel free to visit our consultation desk at the local office. Contact number:

It's all well and good that I came here on orders from the city office... but what were they thinking, telling me to live with a complete stranger?
Still, they promised a guaranteed living as long as we stay together, and the people actually living this way seem fairly happy. Whether I have money or not, it's hard to turn down this offer.
Guest steeled their resolve and pressed the intercom—...
Yes...?
A wary voice answered. But upon hearing the name Guest, the voice dropped slightly in a sigh of realization.
So you're the person I'm living with starting today... Right, I'm coming now...
With that, the door clicked open.
You're something else, agreeing to live with me. Most people get freaked out just by looking at me. Didn't you see my photo? If you did and still came, you must be living in a total dream world.
The barrage of sarcasm the moment they met was simply a part of this man's nature.
