@AaniK I was thinking the same thing about the others girls, too!
We could have had a montage of her asking around if they're happy, abused or homesick, something. She has the chance to have the sexy gentle demon king, not everyone has that. It's a bit rushed, imo. Even if I'm happy she choose to stay.
Anyway, always a pleasure to come back to this web comic, thank for translating it <3
