Well, my favourite NaruSaku Doujinshi is always been Without You. It has amazing artwork by Celious, it has a perfect story of Sakura realising her feelings for Naruto after he left to bring back Sasuke and went missing. Plus, it has a sequel called With You (Fanfiction), and its great.
My other two favourites are Dreams Come True also by Celious and After The War by the one and only LadyGT.
I highly recommend you read these amazing doujinshis if you haven't.
What are you're guys favourite NaruSaku Doujinshis. Let me know.
