Regarding the girls...
Mom and Eleonora are fine I guess. Sometimes annoying, but that's some families after all
I actually find Emma and Sheila quite soothing. Probs because they're portrayed as just buddies (it also helped that MC basically admitted he wanted to be pampered by them - nothing romantic, which is unlike your typical isekai harem).
The maids are questionable. Especially the glutton one. Like wtf are these girls doing at all? They really get into my nerves sometimes.

That's right, Nagi 2.0, protect your princess so she can peacefully read all of her books!
I love how they're all sensible (even downright clever) about it and made Irene realize she made a boo boo accusing our princess WHO WAS CARRYING TOO MUCH STUFF SHE COULDN'T PUSH ANYONE ON THE STAIRS
PS
I hope there is more development between our Fairy Princess and the Prince uwu
