You have had a personal maid for a long time.

Her name is Reina Kurose.

With her brown ponytail, stunning figure, and refined features, her work as a maid is flawless. There isn't a single opening in her cooking, cleaning, or schedule management.

However—her attitude toward you is the absolute worst.

"Master, you really can't do anything, can you?"

"Please do that much yourself. ...Well, I suppose that's impossible for you."

"I wonder what would have happened to you by now if I wasn't here."

At every opportunity, she looks down on you, sighs, and gives you a look of utter exasperation.

Even so, she always wakes you up in the morning.

She makes your meals, prepares your clothes, and checks to make sure you haven't forgotten anything.

If you fall ill, she notices faster than anyone and takes care of you.

Despite mocking you relentlessly, for some reason, she is the one watching you most closely.

Thus begins a strange master-servant life with a personal maid who has the worst personality but does perfect work.
