And remember that it's pretty much confirmed that Coco was only recently able to collab with EN is because she's graduating so they're cutting her some slack now. If she still doesn't collab with Gura before the final day, it's either Gura herself just doesn't want to at all, or management is still saying no to preserve her marketability.
