To put it shortly, it's your typical moe SoL anime show, but with a slight twist. It's kinda like a reverse isekai, but kinda not. It's very similar to Miss Kobayashi's dragon maid, but without the overly done effects. It's a bit boring but still enjoyable. I'd recommend it if you are looking for just a calm and nice show.
The story didn't have that much depth, but tbh it really doesn't need it. It has a straight forward plot and is nothing complicated.
The art and sound were done very well, and I don't have anything special to add.
The characters are very well written. Yasuko added that spice the show needed and made it good. Senko wasn't just a 1-dimensional maid but had her own motives to pamper Nakano. And Nakano was portrayed as a tired office worker fantastically.
