I would like the titles to be either quotes from the book (or in some way referencing them so that book readers sort of know the meaning but virgins don't. The Things I Do For Love would be a great example.) However, now seeing the idea of just using character names I want that. They obviously won't be doing the POV chapter thing per se, as it wouldn't translate to screen well, but having the titles named for characters would be like a little shout out to fans. imo.
