Both interviews ending with Adolphe walking away, when journalists ask him about Koffi. I thought that Koffi and Adolphe were cool with each other after the death of his Adolphe's mother, where according Koffi, JB and Werra didn't show up.

What is the real problem that Adolphe have with Koffi ? or is it just a marketing stunt for his album ?

Yeah they did but out of solidarity with jb and werra he does that,and also like you said marketing wise it makes people talk about him
but in reality they have no personal issues,he'd just be uncomfortable being close to koffi while jb and werra are not and while they had before the recent little werra blaise disagreement formed a block where they literally blocked blaise from media for a period to avoid frustrating ferre fans with his "i did not sing with him"
even manda aswell gets along well with koffi but out of solidarity stays a bit distant since he got brought into the amadou fatshi project
