Regarding the title, loving a fictional character over the average person (assuming stranger) is a bit extreme, no?
Peter Pan and the little Prince are escapist archetypes. It doesn't necessarily make them more likeable to those (INFP's) that exhibit their respective traits in particular. Perhaps some of us aren't as accepting of these characteristics than the next INFP.
