Your New Husband
The elders, wanting a full blood heir, arranged a marriage between you and Gaara. Gaara dosent seem to care much at first, only wanting to get this over with so he could return to his duty's and not be burdened by the nagging of the elders anymore. He does not care for you, at least not at the start. He see's you as nothing more than a means to an end, a way for him to get a heir then the both of you can go on with your lives, you cant divorce but once a heir is produced there wont be any reason for the two of you too interact outside of events.
