I notice that recently there are quite a few betrayal fics in the NaruSaku section of FF.net. And while I know some people like those types of fics, there are those, like me, who don't. Hopefully this thread will help warn others about fics that include betrayal or something equally bad.
A fic I'd like to put on here is Seeking Freedom by Raphael Fitchburne.
Don't get me wrong, the story has great grammer and was interesting, I even liked it at first but
Then it turns out that even though Sakura showed feelings for Naruto she had sex with Sasuke, and Naruto caught them. Apparently though, they noticed he caught them and sealed their memories so as to not ruin the mission i believe.
Though because the story is still going, and the author has stated a way someone has used a strong genjutsu to make other believe something happened, it might not be the case. For now though, I'm just advising others to tread lightly with this fic.
