It's a bold attempt to pull off an audacious unlikely love story of the white business owner and a struggling Nigerian (Yoruba) immigrant single Mum Nurse.
Kudos for the daring, but the script/storyline is sometimes pedantic. The 2 male Nigerian staffs at the firm are surplus to requirements and mostly redundant.
The script writers need better insight into the Yoruba culture and practices wrongly depicted in the drama series...
