>>8774708nobody knows. they were friends and one of the most iconic vtuber duos, then they stopped collabing with each other. that's it. their last stream together was some kind of 3D arcade shill stream, after which they only interacted once more when suisei brought miko along to pekora's mario party stream.
it's never been addressed WHY things cooled off, neighter of them have ever mentioned anything about why they stopped collabing, it's only apparent that they have. everything you read that's attempting to explain anything beyond that is just a rumor or, more likely, some brainsick schizo's delusional fantasy.
