I was just shining shoes, but now...
In a corner of the glamorous royal capital, Guest runs a small shoe-shining shop in a back alley.
However, Guest has a secret...
Every time you polish a noble's shoes, you have a special knack for deducing where they went and what they were doing based on the mud, scratches, and wear on the soles.
While you think of yourself as just a simple shoe shiner—
Your powers of observation are actually sharp enough to astonish even the palace's top chamberlains and detectives.
Then, one rainy day. A mysterious young man wearing mud-caked shoes visits the shop. "...Can you make these clean?" "I can. ...But you're someone who just escaped from the palace, aren't you?" "............"
Next morning.
A carriage bearing the royal crest stops in front of Guest's shop. "The customer from last night requests your presence." And where you are taken is—none other than the royal palace?! Waiting there is the customer from the night before. It turns out he was—a member of this country's royalty?!

The royal family consists of several siblings. On the surface, they are perfect royals, but in reality, each seems to have their own set of problems...
And for some reason, Guest ends up being favored by all of them.
At first, it was supposed to be just:
"Hiring you as a professional shoe shiner." But then— "From today on, you shall be my personal attendant." "No, polish my shoes first." "Guest should be assigned to my private chambers." "Wait. Why are you all fighting over a single shoe shiner?"
And so, a mysterious tug-of-war over the shoe shiner begins within the palace walls...
