I'm Australian, 18 and aspiring to be a writer(some day) and I hope to live in Japan.
Pairings I dislike:
Naruto/Sakura (I am not completely adverse to them, but Sakura isn't really my cup of tea.)
Harry/Ginny, Its just lame!
Ron/Hermione (can stand as long as its not centered on them)
Slash (I'm a guy what can I say)
Pairings I like:
Harry/One of the Delacours
Oh and here is another interesting little fact. I dislike Harems unless they are done extremely well. This mostly applys to Naruto fics. I find that multiple romances centered around one character retracts from the story unless they are dumped/die. Most of the Harem stories mearly focus one one girl, then move to the next while the previous girl takes a backseat. Plus I find that most of the females in Naruto are far too strong willed to be subjected to sharing their man. It just doesn't work. With characters like Ino and Sakura, who actively compete for a man in canon, I just cant see it working. If they were willing to share would they not have done so a long time ago (or atleast try to as that would have required Sasuke's co-operation.) The only Harems I have ever read that truly work are Secrets of a Male Veela and Dakaath. Which were both Harry Potter fics.
