Academy's Undercover Professor WN ch1-ch52 - decent premise terrible execution. MC gets mistaken as professor and he just rolls with it and becomes de facto spy. Hilarity didn't ensue. Author is allergic to world building and if somehow some world building will happen they will be so pround of it that they will repeat it until the end of time. Oftentimes the thing that is described is irrelevant to the plot. There was 30ch gap between information that MC's student had an unique ability and description what it actually does.

Every time MC enter the room he is the most handsome or strongest or smartest guy in a room (usually all three at the same time), speaks one sentence and everyone claps with their jaws on the floor.

2/10 enjoyable trainwreck, won't recommend.
