Looking for heartbreaking fics

[sonten]

Hi guys,

I'm looking for some heawy tissue-alert, heartbreaking, making-you-sob-your-hearts-out kind of Naruto-centric fics. (With SasuNaru or NaruSasu - but hey, if you know some awesome fic of this genre, feel free to share - even if it's gen, or has a differend Naruto-centric pairing as an endgame)
Featuring asshole and/or cheating Sasuke is a bonus.

Thank you in advance!
