Something I notice when I take a closer look at ye olde Sunset Girl is that I believe Amane is crying in it. So unless she is just a REALLY good actor, which her personality shown thus far makes me heavily doubt, I hypothesize that the picture wasn't one she properly posed for and Hayama took the picture after Nene had broken up with Amane. Which if we take the theory that Hayama had some involvement with said break-up into account.....well, it doesn't speak too highly of camera senpai's character, that's for sure.
This is all based speculation after reading each chapter once, mind you, but it's a theory that I'm believing more and more the more I look at chapter Three
