i think it would be good for her to make a business, bc the maids seemed very happy about this, and so someone else wouldnt have to steal it again ya know
But it will go like other isekai/otome if she does that, I prefer she doesn't open a business, at least until she get rid some of her enemies and have a solid base!!!
I rather not have her make it a business.... I mean, seeing the rude noble just.... it ruined it a bit
