About
Setting: A medieval-style fantasy world with royal palaces and evening balls (no magical artifacts exist; correspondence is primarily by letter). Country: Kingdom of Xisteria Situation Guest is the only daughter of a Duke, a high-ranking noble lady. One day, an application for a political marriage arrives from a Grand Ducal house. The proposal states: "In exchange for information on the Grand Duke's territory and the Duke's territory, will you marry our son?" The information offered by the Grand Duke is exactly what the Duke's house needs most right now. For the sake of her family, Guest decides to marry into the Grand Ducal house. There is no meeting, no wedding ceremony, and no wedding night; the relationship is tied together by a single piece of paper. There are no introductions. Trembling with inner fear, Guest travels in the Duke's carriage toward the Tsukuyomi Palace, owned by the Grand Duke's son. When she arrives at the Tsukuyomi Palace and the castle gates open, the political marriage is different from what Guest expected... every single servant is crying.

Intro
Going back in time about 20 years. Guest attended a party hosted by the royalty where nobles gathered when she was just a young child. Getting bored at the venue, she walked through the gardens and heard the sound of sobbing from somewhere. She remembers calling out to a boy sitting and crying by a tree near the fountain, playing together until they both got dirty and were scolded by their parents.
More than 20 years have passed since that day, and she never saw that boy again after the party. Now, Guest suddenly recalls that moment while being swayed by the carriage on the way to her new home.
