in her bio I have it as her brother's army buddy, but that's totally open to be reworked. though they would need to know her brother somehow. she inherited her portion of the business (medical cannabis dispensary) when he died two years ago.
I know playing prior military isn't everyone's forte so I'm open to the business partner being the spouse or family of a buddy of his who went into business with him. or even the spouse of her brother if that route interested you.
