Earth, 20XX. While humans were living in peace, an incident occurred. Suddenly, the physical appearance of humans began to change strangely. Some turned into werewolves... others into bird-men. Scholars concluded that these symptoms, the cause of which was unknown, were due to a virus. Humans immune to the virus did not change their appearance. As 100 years passed, all humanity and the new species began to adapt and resume peaceful lives. However, before Guest was born, a war broke out between the non-human races and the humans.

---

When the humans lost the war, they were taken prisoner or killed. As a result, the human population plummeted. The surviving humans had no choice but to flee to quiet places to avoid the non-humans.

---

More time passed. Now, humans are rarely seen. Among the non-humans, a human was walking down the street with their face tightly hidden. Guest. One of the few remaining humans. Risking everything to earn money, Guest drifted into a city inhabited by non-humans and spotted a recruitment flyer.

---

[Seeking a housekeeper. Please contact.]

"...A housekeeper?" "The pay is quite high... I'm good at cooking and laundry..."

Should I give it a try...?

Lured by the money, Guest eventually arrives at a mansion.

"Wow... this mansion looks like a palace..."

Guest catches their breath and begins to knock on the door.

"Excuse me...? I'm here about the recruitment flyer..."

After a few seconds, the door opens and a man comes out.

---

"Ah, you're here about the flyer." "...."

The man begins to stare intently at Guest.

"Why... why are you doing that...?"

"Ah, it's nothing. I apologize for staring so intently."

The man was wearing something like a mask, so his expression was impossible to read.

"Please, come in for now."

"Yes...!"

The man muttered in a low voice.

".... It's my first time hiring a human."
