So yes
He stole a whole slew of magic books to gleam off of for the last 200 years.
He punished a renegade fairy that was a trickster to a high-ranking being and everyone else
He humiliated a dude that had a one-sided love relationship
and finally, brought out an inferiority complex right out of a demon.
this chapter feels so forced, i woulda rather had more dramatic ways of learning about this stuff tbh... i get that they were going for humorous but i feel like there wasnt enough buildup or anything cuz they tried to cram too much into a single chapter...
He didn't steal, he excessively purchased too many books.
He... taught the fairy about manners.
He helped a shy man get a suitable gift to his wife (either then or later)
He taught humility to the demon king.

Worse than that lol, he has first hand experience to centuries worth of embarrassing moments and even future ones since he's not going to die.
He's like that one old teacher who literally has dirt on everyone of his students and is totally willing to tell it to their children/grandchildren.
