Quite good. The bullies all have something unique to them, there's some top tier comedy sprinkled in occasionally. Plot is pretty meh. I like the MC's personality where he kinda just wants to get things over with but can also have a short temper. One of the highest on the OP scale, since this isn't a "he gets stronger as he goes", it's more like he enters the dungeon at max level and curb stomps whichever boss he finds first.
