Honestly, I will read anything you want me to. I will give advice and all that crappy feely stuff. 
I will even read stories where the guy gets the girl in the end. I won't think much of it, but I will.
I like stories that have plot twists, where everything doesn't tie up nicely in a little bow.
I want to be reaching for that tissue box.
Make me want to feel something.
If you can make me feel something worthwhile, I will star every single one of your chapters, recommend your book and also add it to my reading list.
and as you can see, not many books are on said reading list

books I will not read are where the plot goes similar to
"I'm just a sweet innocent girl, I hate this dude, but I'm oblivious to the fact that he loves me, *goes away from usual scene* he isn't so bad, I guess we can be friends *traumatic event* OMG i totes love him, I'm going to kiss you forever. nothing will tear us apart *epilogue * we have a perfect life and thousands of babies"
