Needs proofreading, yeah. Especially with the pronoun parts. Otherwise, happy to see more of this.
Y'know, this was actually a great chapter in terms of moving forward. Leon inadvertently gave the two idiots a kick in the rear to get their act together and recognize him. Of course, he's an idiot who doesn't realize how earning as much favor as he does causes rapid promotions, but that aside, he got a MacGuffin and dealt a potentially lethal blow to the family of obnoxious nobles that were harassing Angelica and Olivia.
And...then there's that part. I don't mind the trio being so introspective, since it can lead to results like the idiot duo mentioned above, but when they're just letting a random bitch's insult stick for so long and, above all, stop communicating because of it, it becomes simple moping and melodrama, which honestly should be done with around now.
And the crux of all this is, in the end, Leon stubbornly calling himself a Mob for some reason I don't quite get. Just fucking tell the girls the truth to explain your actions dammit.
