Well, I know this has been asked before, but I just wanted to specify my question a bit. Is there a novel where the protagonist is a teacher or spends a significant portion of time teaching, in which he is either not aided by a cheat/system which does the work for him, or he is actually heavily invested and devoted to teaching his student. For example, I do not want a story like OPM where Saitama is a teacher in name only, or one like My Master Disconnected Yet Again where she only gives lackadaisical advice which only succeeds due to the student being a genius, or one like Library of Heavens Path where all the resources and material are basically provided for the MC to use as posturing tools at his convenience. Instead, something like RAFTH where he actually does stuff to teach (in a way), or even that bit at the start of Skyfire Avenue where the MC pretends to be a teacher but still prepares well written and researched speeches which capture the students attention and educate them with his own abilities. tl:dr is there a novel where the protagonist is a teacher who actually cares for teaching his students and is not given his ability to teach through op cheats and must instead work for them?
