Its just a weird decision to have this be her last project. The MV is well animated and she has a nice singing voice that you really cant help but wished she bothered to use during her time at Cover, but its not something I'd play more than once with how angsty it feels. I dont think most of her fans were that demanding and expecting of her, they just wanted to see her with some degree of consistency. Whether it was just her playing vidya or even doing a simple zatsudan 3 times a week, once biweekly or even monthly, they just wanted to see her do anything. It hit a point where some chumbuds sent superchats to other EN members because they wondered if even her coworkers knew what happened to her. Maybe its entitlement, but its also understandable considering they had paid memberships running and didn't want to throw their money away for their favorite entertainer to just sit on.
I'm probably reading into the lyrics too hard for whats meant to just be a cool anime song written by the DMC5 guy. But unless she had incredibly low blood pressure or was a chronic narcoleptic to where everyday life was difficult for her, or unlessCover had her working like a slave 24/7 off stream, it didnt seem like things were that bad for her either.
