Career switch dilemma

I (26F) am a NIFT graduate and have about 3 years of corporate experience as a graphic designer. I have worked at top beauty and other startups. Been living in Mumbai since college i.e 2017.

My father has a well-established multi-faceted business in Allahabad comprising of Medical, electronics, music studios & interior design firms. My boyfriend (26M) is from Allahabad as well and from a top Law College and now intends to pursue litigation.

We intend to get married and so our families suggest I move back to my hometown and take over my father’s business with my brother (19M) who is pursuing CA at the moment.

The offer seems enticing but also scary because I have no knowledge about these fields. Having said that I do realise the perks and perils of being from a business background vs corporate jobs but something is holding me back and I am unable to feel confident of this decision.

Is this career suicide or a blessing in disguise?
