As I've already written in discussions in other chapters, with this setup, it's just impossible to make the party not seem like assholes.
If you really want to solve a misunderstanding there are other than times and places to do this, maybe after the person has calmed down a bit. It's also not limited to times when you coincidentally meet the person somewhere. You could arrange a meeting, write a letter or even involve a third party.
I accept that you like the story. I was also looking forward to a story which is different to the typical banished story. But in my opinion the author made so many mistakes that the story is just unbearable.
- Except for Athena, who hurts him the most in the end, he has no friends in the party
- from his point of view she betrays him (kicking him out is already enough + possible love affair with Daru)
- from his point of view, Daru betrays him, because he knows that Est loves her and starts an affair with her
- elf girl openly dislikes him because he's close to Athena
So tell me one reason why he shouldn't hate the party. The left him with nothing. They had the choice, Est didn't. I don't intend to hate the victim in this story for the sake of the "let's sympathize
with the banishing party"- plot, because they are clearly at fault (especially Daru)
As was already mentioned, everything could be solved with one discussion with all party members but to continue the story all character (also Est) act amazingly stupid so much that it hurts. The author just wanted to include too many topics (love, friendship, rivalry, training vs op power...) but the story is so shallow that he didn't even manage to achieve one.
I'm don't think this one is particularly good or bad. It's just annoying most of the hate and downvotes it gets come from people not buying into the concept by ignoring events or overly sympathizing with Est. Yeah, he feels bad, but he's also factually wrong outside of his sudden powerup.
He might have the point of view that Daru betrayed him to pursue Athena but that was a conclusion he came to in a circumstance he should not have created by returning to their house in the middle of the night. It is also, of course, wrong and he wasn't willing to listen at the time. He was told again later when they met at the guild counter that it was a misunderstanding and ignored it. Your suggestion of having a third party wouldn't change anything as it's just a third party reiterating what has already been said without anything to contribute.
His feelings of betrayal from the idea of Athena being in a relationship with Daru also aren't based on reality. Not only is it not true, but he was also never in a relationship with her in the first place. For kicking him out, the manga version doesn't convey it well, but this wasn't something out of the blue, he knew this was coming because of how he was performing. He was trying to compensate for it by doing other work, but the situation was getting more dangerous like that until he nearly died before the start of the story. Were it not for his sudden change from how he's been all his life, it would be clear that he just could not survive doing this job. He knew this.
For the elf girl, it's also partially Est's fault on that one, though she only mentions it in passing. As a buffer or support, Est doesn't treat them equally or fairly. Whether it's his crush before or resentment now, he has an unhealthy preoccupation with Athena and prioritized her to the exclusion of the other two. Her being attracted to Athena too might lead one to think it's just another lesbian character interfering in the main couple's romance but that romance isn't real while her criticisms of Est as a partner/coworker are.
So, the fault for the banishment itself was mostly on circumstance. The way Athena handled it was actually proper for these kinds of situations, explaining it to him in a neutral and matter-of-fact manner. You aren't supposed to get personal or be long winded and the explanation was sufficient for the context. Est only acts surprised because he's been in denial and quickly became hostile. He then has an extreme and unreasonable response by throwing himself into a situation he knows he would die in. This isn't their fault either as they made the decision and kicked him out by the book, the way you would be taught in HR. He then showed up at their home in the middle of the night and just opened the door, came to the wrong conclusion from what he saw, then refused explanations both at the time and when they met later. They aren't the ones at fault.
Though, again, I don't think this story is particularly good either. I just think that a lot of the criticisms are wrong in that they are based on incorrect information. It does have an interesting concept that's worth exploring but it isn't doing as bad a job exploring it as you suggested, even if not great. Honestly, outside of the best, it's mostly mid stories that have the most worthwhile conversations to be had. There was a WN that finished awhile ago, HUGE FREAKING HOLY (all one noun). An interesting concept (rather than just the mc getting banished, its massive layoffs throughout the country as royalty pushes for automation
and to get ride of an international armed organizations like the adventurer's guild to maintain the monopoly on violence governments are defined by.) and side characters (two of the mc's students and a weapon anthropomorphized into a girl
create a phantom thief troupe to do stuff like steal/redirect newly discovered geothermal vents and newly formed rivers from a prosperous country to a poor one just to prove that it could reverse the poor country's desertification.) However, the mc is frustratingly detached enough to make it mid. For example,
he admits that he can't have a relationship or have children because he would actually abandon the child the second he got bored of 'teaching' them as a hobby. 'Teaching' here mostly being going up to generic banished mcs and telling them a matching generic use for their skills before he fucks off and pretends they don't exist. Also, the title is fucking stupid. Well worth talking about.
