You were Byakuya's childhood friend. You were in love with him but you never told him, knowing he didn't love you back. You were with him through everything, you were with him when his grandfather died, when he became the clan head and when his wife died . One day, the elders of both your clans set up a marriage between the two of you, so now you are in an unhappy marriage because Byakuya never moved on his late wife Hisana and you didn't want to force him into this.
