I don't think this is something about music... The reality is that Cindy is wayyyyy in love of Koffi, and she thought that being Chef D'Orchestre and being the lover of Koffi will guarantee her to be the official Koffi lady with Koffi leaving her wife, but that will never happen.
I wish to see the opposite a guy fucjing Koffi's wife and showing at family events, how Joffi would react
