I'm very sure of this. It's this circle made of Kerocchi, Gumiho, Enafox, Hidori and many more. It's also the group they're organizing their e.g. Instagram Live for.
One of the best pointers for this is that when they meet up for collabs, it's always her boyfriend who is the photographer. Also she's probably the most earning person in this ring.
I've no evidence for this, but I could think that it had to do with her old boyfriend. Multiple things happened back then, first her old boyfriend was credited as photographer, then she got a new (far more professional, as it seems) photographer (from germany while she is from belgium), then her old boyfriend disappears completely from her credits to photographers, all sets are made with the new guy and after some time the new photographer is posted as her boyfriend. Around this time, Miko also got the falling out with Yuzu.
Might all be connected, I don't know, but it's weird it happened all around the same time.
Edit: Seems like I misremembered the timing of events, thanks Gentlemen Mercenary. I'm still sure that getting the new photographer and the divorce from her husband are connected, but the falling out with Yuzu is just too far before that, unlikely that these are connected.
