"What kind of books do you like reading?!" Princesia asked excitedly.
After Penny mentioned a discreet type of book to Princesia, a book that isn't famous yet the story is for book nerds like Princesia, making Princesia geek out as she loves the story of that book, and she didn't need to ask Penny if she likes books or stories as it solidifies that she likes books too.
"Oh, I like non-fiction ones since I came from the mortal world, I like fantasy stories and sci-fi genres, even action since unlike our Angelic Combat, human combat style is extremely different since we don't have wings in the mortal world," Penny answered.
