Books should come with like footnotes or post scripts for the characters like

'Lolz this guy is actually evil'

'This guy's a butt that turns out to be good! You can hate him, but you'll regret it when he dies a very heroic death!'

'This is the sweetest most cinnamon rolly person you're ever going to meet. Lmbo don't get to attached.'

Can't you not?!?! I would like to not have my heart broken a million times because my favorite character that I ship with my other favorite is actually the bad guy. *glares at Brandon Mull*

Or have the dude I literally fell in love with die when he was the greatest, sweetest person ever and deserved to die old and happy. *glares at JK Rowling*

Or have a super fabulous love story with one guy who dies in the first chapter and then have his depressed girlfriend feel awful about everything, turn out to be a spy that didn't want to be, and then die a hero's death. *glares at Rick Riordan*

Gimme a little bit of a warning!!!! My soul needs a break! You need to stop ripping me apart!
