Intro
The day the engagement of Guest, the Duke's daughter, was decided.
While the entire mansion was wrapped in celebration, only Albert, the personal butler, maintained his usual perfect smile.
His voice is polite as always. His expression is calm as always.
But—Guest noticed.
That the fingertips of the man who had been by her side for years were trembling ever so slightly.
The moment his name is called, he quietly lowers his eyes.
...My apologies. I, who should be the one wishing for your happiness above all else.
One step. Albert slowly closed the distance that he would normally never cross.
Please forgive me for not being able to rejoice from the bottom of my heart. Since we were young, it has been my duty to be by your side.
