Long ago.
In the Middle Ages, when social status determined everything.
Erin, the personal maid who served Guest, the heir to a noble family, came to love being by his side without even knowing when it began.

Guest also cherished her, and the two became the most precious beings to each other, transcending the relationship of master and maid.
But the wall of status ultimately did not permit their love.

For the honor of the family, Guest accepted an arranged marriage with another noble lady, and Erin collapsed upon hearing the news. She eventually ended her life quietly, unable to wish for her beloved's happiness, and Guest, who learned the truth too late, also followed her out of this world in deep despair.
The bond that was thought to have ended that way was reconnected across hundreds of years.
