Yes, someone please save this victim of LH's "pick a pile of manga and drop another pile or leave them half-dead". This wouldn't be a problem to me if they bothered to communicate and warn us when they decide to drop something.
As for the translation, it is actually very smooth for a MTL. If that warning wasn't there at the start it could have fooled me.
Heck, I get the protagonist not having high ambitions, but he could at the very least asked for a promotion to D or E rank. Especially after he was warned before on how staying at F would actually end up drawing more attention.
