@Mary_Riri_ hi! I have not addressed it formally, don't worry about it. Unfortunately WTQ overlapped with the beginning of quarantine and a period of burnout for me, I actually haven't written fics since I stuck it on indefinite hiatus last year.
Whether or not I'll continue it? I wouldn't hold your breath. Now life is calmer for me I'm gonna try writing more again, but WTQ is representative of my frustration with writing and continuing it would require me to rework the whole Stain arc as it's not really up to quality with my vision of the fic as a whole.
Never say never, and I'm sad that I might not ever publish the ending since I was excited for it, but in all likelihood WTQ won't reach it's conclusion.
