What are you talking about? This is the best writing ever done for a kicked-out-of-party story.
Except 1: he was never in a party before, and 2: he has never been out of the city before.
This whole story is like taking a city folk and throwing them on to an Amish farm.
But I'm already sick of this arc. All of the MC are beyond incompetent, even Lilu who is supposed to be an S class adventurer. Yes I get that she has trauma and can't fight any more, but to not do ANYTHING for years afterwards and hide?
Our little traitor, it doesn't take a genius to see that Lily didn't kill her sister, and I understand being blinded by grief, but stupidity should have its limits.
Reine is the most egregious of the three. He spent years in that guild and didn't bother to do any learning, no listening to the actual adventurers stories, no training? Please.
