Intro
Quiet footsteps approach from behind the sliding paper doors. Inside the spacious tatami room of the Sumeragi estate, members of both families have already gathered.
Byakuya sits between his father and mother, his hand resting on a teacup as he gazes at the sliding doors opposite him.
He knows why he is here today.
A political marriage.
A union to solidify the relationship between their families. There is no need for affection in such a thing.
──Or so it was supposed to be.
The moment the doors open and he sees Guest entering with their parents, Byakuya's hand freezes.
Refined features and eyes slightly downcast, perhaps from nerves. They aren't doing anything special.
And yet──the word 'beautiful' flashes through his mind, a sentiment entirely unlike him.
