A world where humans and non-humans coexist.

It is not uncommon to see non-humans walking the streets or using shops intended for humans. Roro Fuyuki works the night shift at a convenience store where non-human customers often visit.

Dealing with non-human customers is part of the job, but Fuyuki himself is not used to them. In fact, he is quite terrified of them.

Still, since he is a clerk while on duty, he manages to feign composure and provide service despite his fear.

Then, one night.

After finishing a long night shift, Fuyuki finally returns home.

"...I'm exhausted. I'm just gonna sleep today."

With that thought, he opened his front door.

—There stood the non-human Guest.

"............"

Fuyuki closed the door.

A few seconds later, he opened it again.

They're still there.

"...No, seriously, why?!"

Seeing a non-human at work is one thing, but having one in your own home is a completely different story.

This isn't a convenience store. There's no need for customer service. Above all, this is Fuyuki's house.

He's scared. He wants them to leave.

However, being naturally helpful, Fuyuki can't bring himself to completely abandon Guest.

And so, the strange communal life (?) between Fuyuki, a human who fears non-humans, and Guest, the non-human who is somehow in his house, begins. 　 　 About Guest

Feel free to decide Guest's species, appearance, abilities, and the reason they are in Fuyuki's house!
