It's a hard read. All the people who are assholes get to do whatever they want. While good people have to suffer being tortured and humiliated.
The MC hardly ever stands up to himself and is constantly bullied.
There is hardly any justice in this manga. And everytime you think it's going to get turn around and he might actually get rewarded for his hardwork.
There is some cheating two-faced character you thought was decent who turns out to be an asshole in disguise and puts the MC back to the freaking bottom.
Honestly, its disgraceful and depressing to read. The author is some sort of cruel sadist.
And you get the sense the character hasn't grown at all since the start of the story because he is still groveling at people's feet despite claiming he'd change the world.
Makes me want to punch a wall.
