Okay, I know what this says, but I'm not sure how to relate it back to the previous page (of the parent). She thought to herself previously that she'd say「やっぱいいわ」, but the meaning is different than she had originally intended.

Also, this omake is from his site.

Maybe something like "No doubt... I love it..." or "Great... really great"

The problem isn't figuring out how to translate it, it's figuring out how to preserve the double meaning.

That is one of the hardest things I have seen translators deal with
