I mean, i wouldnt mind a analysis of it all if it can be done in a non /vt/ shizo way. I didn't really watch the woman, but im still curious.
Best as i can understand she felt overwhelmed by the popularity?
Gura felt pressured by the role.
When she stepped back briefly her fans and the internet in general began to complain she wasn't streaming. Gossiping about how she was over etc... Hence the fading away the memory of her etc.
The burn it all down / tear it down is a mixture of her feelings of just stopping streaming in general and retiring then and there but also the negative people online towards hololive in general.
The abyss in which she hides is just her not being on her social network accounts trying to avoid it all the best she could. Holing herself away from everyone and everything.
Theres a point where she was about to leave but she stopped herself probably because of the negative feelings of burn it down tear it down and her fears what it would do towards hololive etc.
Myth steps in as she descends into the abyss once again and gives her support those are the talents that were there for her.
Eventually she finally worked up the courage to call it quits letting herself do it and no longer fighting herself over it.
Hence opening the door and turning the Gura career to ash by not being affiliate.
Its not a sad ending though as she's clearly going into something new with the door opening but we don't know what it is and neither likely does she because its a blinding light. But it is a light.
