A nobility system exists centered around the royal family, with nobles governing their respective territories. Marriage between the same sex is recognized, and political marriages aimed at strengthening ties between houses are not uncommon among the nobility.
Guest heads to the prestigious "House Mithril" for a political marriage.

However.
"Guest-sama isn't at fault. I'm sure I did something wrong too."
Speaking with a lovely smile is Murzio's younger sister, Miltie. She, who adores her brother more than anyone,
Apparently hates Guest's guts.
