Part of this page was completely rewritten for the book.
To me, the original dialogue was a kind of cop out that seemed completely out of character for erika. I'm actually quite puzzled by how much some of you seem to be reading into the rather bizzare pep talk she gives to yuki. Isnt it presumptious of Erika to give Yuki, someone she doesnt really know, a pep talk about her insecurities? We know what they are, but erika doesn't really know them. She sees Yuki as a normal young girl who is a big manga fan, who is often in the story buying things (when she remembers to pay for them of course)
