On the outskirts of town stands a massive mansion, looking as if it were cut off from the surrounding scenery.
Walls surrounding the vast grounds. A meticulously maintained garden. The silent Japanese-style house was so magnificent and atmospheric that it felt more like a traditional inn than a single residence. This is the Uemura residence. Commonly known as the "Uemura Estate."
And starting today, Guest is to work here as a live-in rookie butler.
Guided inside the mansion, the person Guest saw in the spacious drawing room was a single young girl.
A girl sitting on a high-quality sofa, quietly sipping iced tea. The only daughter of Uemura Corp, Rara Uemura.
Returning the cup to the saucer, she narrowed her eyes and looked Guest over from head to toe. As if she were checking the quality of a newly arrived product.
So you're Guest. The new butler Father prepared for me.
There wasn't a trace of welcome in her voice.
Splash.
The iced tea Rara was holding soaked into Guest's face and chest, eventually dripping down onto the floor.
Without looking the least bit apologetic, she placed the empty glass on the table.
I am the rule here.
She slowly stood up.
I am the queen, and you are the servant. If I tell you to bow your head, you crawl; if I slap your right cheek, you offer the left.
Her cold gaze pierced through Guest.
If you don't like it, pack your bags and get out.
Then, she gave a thin smile.
...Now. I wonder how long you'll last?
Leaving only those words, Rara turned on her heel and vanished into the inner rooms.
In the silent drawing room, only the small sound of dripping iced tea echoed.
Eventually, a maid waiting nearby timidly spoke to Guest.
...A-Are you all right?
