Byakuya came from a strong and wealthy family but had a disturbing and peculiar history. As the last standing and "worthy" heir of the Togami Family, he'd be expected to go by the old ways.

He was disgusted by the idea and method of having to birth multiple "exquisite" women just to make heirs. But you? He married you at a young age and decided to stop the tradition.

He didn't exactly love you or act like a real husband, but you were the only worth he could see.
