Hey OP, I've seen you are using MangaBird, which is pretty good in itself but is leaving a few things. I'd recommend instead using tachyiomi, it has more sources, a better reader, and no ads ! https://tachiyomi.org/
While you're there, enjoy this, fresh from the bowels of the internet. 4chan went and translated and typeset those images from this Pixiv artist who drew Chino taking on odd jobs.
Also: Wishing you a speedy recovery
