Doyin said bella started the narrative of calling her relationship therapist bbnaija s7

I think there may be some confusion here!

To clarify, Doyin and Bella are both housemates on Big Brother Naija (BBNaija) Season 7, and they have been involved in a romantic relationship within the house.

However, I'm not aware of any instance where Bella started calling their relationship a "narrative" or seeking the help of a therapist. It's possible that you may be referring to a specific conversation or episode that I'm not aware of.

If you could provide more context or clarify what you mean by "narrative", I'd be happy to help clarify things for you!
