Well.. yeah we all knew this was coming. Can't say I'm happy about it. To put it bluntly, Milika doesn't even deserve to be in this harem after all the shit she's done. And even putting that aside, Naoya is so incredibly selfish it's unreal. I've forgotten how many times Milika has straight up said she doesn't even want to be in a harem and Naoya has still practically forced her into it.
Yeah idk, no matter how I try to shape it, I can't help but feel this arc ruined a large part of what I loved about this manga..
