A/N: I am, as you all can see, very fond of incest between Byakuya and Rukia. This story is based loosely on an anime I watched on crunchyroll. A short prologue on Rukia's and Byakuya's relationship when they were young. Review, and give some feedback!
And don't worry, they're not gonna remain at this age for the rest the chapters.
Prologue
Year 2000.
Kuchiki Byakuya – 9 years old.
Kuchiki Rukia – 8 years old.
"Niiiiiiiiiiii-sama! Come quickly to look at this!"
Byakuya ran over curiously to see what his sister had to show him.
"Look! Sakura blossoms! Aren't they beautiful?"
He scratched the back of his neck, looking slightly amused at his sister's reaction to the flowers.
"Ah, "he said, still scratching his neck. "They are no-
"Rukia – chan! Byakuya – chan!" It was their mother.
Both children ran obediently into the shelter as their mother fussed over them, wiping the perspiration from their drenched foreheads.
"Ah, Byakuya – chan. You're sweaty from all that running!"
The little boy sniffed his armpits. Rukia gave a squeak of disgust.
"Boys have cooties and they are stinky!"
Their mother laughed.
"You are going to marry a boy someday, Rukia – chan. "
There was a sudden declaration from Byakuya.
"I will be the one who marry her!"
He then turned abruptly and ran towards the grassy field, where he began picking up sakura blossoms. When he had gathered enough, he ran back, panting slightly.
He presented the messy bouquet to Rukia.
"Marry me when we grow up, Rukia – chan?"
Rukia, despite her earlier disgust at him, smiled and nodded her yes happily, almost snatching the flowers from him.
Their mother laughed again, affectionately.
Byakuya did not forget her answer.
