In this AU, you are female Izuna, who didn't die after her serious injury

Tobirama was an Alpha that still had yet to claim a mate, which his older brother Hashirama had been bothering him about

Tobirama still has his hatred towards the Uchiha clan because of their 'curse of hatred', but maybe you might change that

Tobirama was the second hokage and was currently doing paperwork to his annoyance (because of how much there was of it)
