May I know why?
Amon punishes Na-in in the most humiliating way possible to him
What kind of punishment?
In the upcoming chapters, Amon misunderstands something Na-in did as Na-in trying to escape him and decides to punish all the battle priests that were in charge or guarding Na-in. They would've died if not for Na-in requesting Amon to punish him instead, and Amon lets Na-in decide how he gets punished (somewhat). And so Amon punishes Na-in by giving him head but then proceeded to say something like "it's not a punishment if you enjoy it" and so he shoves fruits up Na-in's ass. Which is incredibly embarrassing and humiliating for Na-in. This is the beginning where Na-in's hatred and resentment for Amon finally takes place.
where did you read the novel?
I want to avoid putting links here as there may be issues, but you will be able to get results if you just search "The serpent that swallowed the snake novel". I would recommend the second site that comes up, orange one. After that, for the side stories you can read from the third site, the purple one. (This one is a bit hard to use so be careful for spoilers) The novel unfortunately hasn't been translated by a human but AI so mistakes are to be expected (￣∇￣") hope that helps!
I am actually going to cry wtf is wrong with that reptile freak, I hate him, Nain doesn't deserve this he is so kind :( I hope he runs away with gwen and amon's reptile ass goes bald and tweaks and he explodes
I actually can't hate Amon, I guess this is a quality most people who have finished the novel have
wtf
Amon's going to get mass hate in the next chapters. You stupid dragon...
