Some small part of me was hoping she'd come back, but I mostly figured it'd go this way. Personally speaking, if I were in her position I'd be too embarrassed to return - even if I had mended my private relationships with the members.
I'm glad she's sticking around though. It's probably going to be hard work moving forward since it was all so public.
I will miss her voice quite a bit, but I'm less worried about Tsubaki performance-wise than I would've been 2 years ago; it'll take a second to properly find their footing, but "Premier seat" was great and they did fine at that collabo event with STU48.
