More like it's obvious coco is a literal traitor after spending months trying to sell the "I'm just looking for creative freedom and I'll never join another company" neutral stance. She announced joining vshojo literally to the day of the 1-year mark of her leaving, that looks exactly like shitting on a non-compete clause of a contract.
Coco may like PPT but PPT is not obligated to love kson forever and ever, I notice that people on youtube, reddit etc seem to have this absolutely fucking retarded way of looking at vtubers as if they're cartoon characters sticking to written roles/rails. Their friendship was one of convenience, that's all. They aren't married, and coco not only left but has walked all over shit she said she would never do multiple times - and that is what is -known- to us just as viewers watching what she voluntarily puts out. Who knows if she tried to badger/bully ppt behind the scenes into backstabbing Cover and she just didn't wanna. Unlike Coco, Kanata actually cares about the idol stuff and is one of the most devoted in entire roster to it, vshojo has NOTHING to offer her at all vs getting songs, concerts etc meaning the world to her with Holo.
