Good. Maybe now those four worthless, shameless, sociopathic mobs can leave the story or at least return to the background?
Her reaction, by all rights, should only intensify in negativity: all four are trying in earnest to cuck her. Three of them know that Nobuyasu is her boyfriend, and are still trying; one of them in particular passes herself off as Mone's friend, claiming to have accepted the two, and is still trying.
It's also funny that Psycho Flatchest would comment on female friendship at the end; this is the kind of thing they'd do to each other with smiles on their faces all the while. Even funnier is that she thinks that male friendships are no better, when women are always desperate for male companionship without romance--but that's for no reason at all, right?
