What Did I Do in My Past Life to Marry into the Kuchiki Family? [Crossover]

The blurb is exactly as the title says.

Or, to put it another way:

What did I do in a past life to deserve marrying into the Kuchiki family in this one?

1. Pairing: Byakuya.

2. The Thousand-Year Blood War is airing, and I realized my heart had died. Kubo, give me Ichigo and Rukia back! Give them back to me!!!

3. Updates whenever I'm angry and feel like it.

4. Warning: There will probably be a "Do you love me or them?" plotline, along with some fantasy career plots that aren't supported by much concrete detail. This isn't a career-focused story, anyway.

Theme: Be a good person. That's all.
