I agree that this is gonna be the hardest thing for Cari to write in a way that makes sense. But I really do hope that a full harem ending won't be possible. A few rare pairings that make sense are fine, but in all other cases I am waiting for some kind of dismount point (heh, literally) where we have to decide who to go for and who to say goodbye to.
How to write this without creating bad blood and hurt feelings, I seriously wouldn't know. I'm really glad I'm not the one who has to figure that out.
There's no need for updated signatures. All hail the queen. The point in time matters not.
You know, I still have this theory that Cari used the funds from OIAL to buy HS asset packs. Hundreds of them. And the only reasonable way to utilize them is creating a place like Eternum that has no clear visual identity, but many different ones. A genius move if I do say so myself.
As someone else already said, I still think Annie is the least interesting. Has no bearing on her being incredibly attractive and cute as a button but from a lore standpoint she's kind of bland right now. I'm sure it'll be rectified in the future though.
