Now that I'm at the end of the pirate arc, my opinion hasn't really changed. Pearl is subjectively more attractive than Kira though that isn't really any sort of criteria the MC would use, especially when it comes to his rage issues anytime Eliza is fucked with.
I guess I just expected him to intimidate her, threaten her, do something, even if in the end it's all bark. She's not even gone 30 seconds before he's all "she's my friend" don't worry. It's less than a month after Selena's betrayal and here he is, learning absolutely nothing. By the end of this he should come away with major trust issues.
That said, I still enjoy the story. It's not at the same caliber as the earlier chapters, the MC just seems inconsistent.
