IIRC, she's brought up that she moved back in with family. That in itself is a basket case of complications when it comes to a career in streaming. Personally, I think her stopping streaming is a healthy mix of:So shower thoughts, she was pretty explicit that not only can she appear in stuff once in a while, but that she might consider coming back to Ame permanently if she wanted to and Cover would have her.
So what scenarios would lead to that. Would she be more likely to come back if she's successful as Dooby3d and gets all her creative hungers satiated? Would it be more likely if she 'failed' as Dooby (abject failure seems like an impossibility for a Holo who left on good terms and wants to continue content creation, but I mean more like how artists tend to hate their own work and are never satisfied with it)? Would there be any reasons Cover would say 'no' if she asks them to come back (like Dooby3d is actually obsessed with doobies and smokes pot on stream non-stop)? Etc.
Just some hypothetical thoughts.
a) Cover putting their put down on new unauthorized 3D models (though her previous ones were probably grandfathered in)
b) Complicated set-up at home severely impacting her usual routine/workflow/schedule
c) Pent-up creative itch/projects she can't really scratch/pursue while under Cover's schedule & management guidelines with all the "homework" and deliverables they have to do offline.
For shower thoughts of my own, is her "3D studio" just a spare room in her previous place that she just set up herself or did she get a rented space for it? If it's the latter, could she be taking some time off from streaming in order to actually focus on setting it up as a commercial venture that she can manage and eventually rent out to 3rd parties as well or officially contract it with Cover.
