From what the title says Koffi fellout with Papa Wemba because Koffi wanted to sleep with his wife and that is the same reason why the relationship with Wazekwa too, I don't want to cause controversy but only know the real reasons why Koffi fell with his mentor and the other guy who helped his career (Wazekwa)

title is partly clickbait at some point she asked about how he seems so strict and radical when he is upset and how he does not want to make peace with koffi and how papa wemba and koffi were enemies  before his death,and he said there are things you cant forgive easily like for example somebody you take as your friend approaching your woman or you daughter and other things and that he did not want to go in details  out of respect for papa wemba's memory(wazekwa indirectly referred to story papa wemba said indirectly himself  in several interviews that allegedly koffi approached mere amazone in france and that he saw the messages ) and that sometimes we should not judge when somebody is strict on his decision maybe he has good reasons,so they used it as a question,while wazekwa did not say it let alone saying slept with,he even threatened to sue that site only calmed down by shaka kongo
