Wait I’m suppose to write something here
Well I guess I can say I don't really write much, I do have something planned but I have no idea when I'll have time for it.
Allen x Lenalee (D.Gray Man)
Roxas x Xion (Kingdom Hearts)
Len x Rin (Vocaloid)
Mukuro x Chrome (Katekyo Hitman Reborn)
Clint x Natasha / Hawkeye x Blackwidow (Avengers)
Some side pairings:
Miranda x Marie (D. Gray-Man)
Aqua x Terra (Kingdom Hearts)
Namine x Riku (Kingdom Hearts)
Sora x Kairi (Kingdom Hearts)
Kaito x Meiko (Vocaloid)
Luka x Gakupo (Vocaloid)
Tsuna x Kyoko (Katekyo Hitman Reborn)
You can look through my favorites for some quality fanfiction on these pairings.
I'm not really "anti-" any pairings, I tolerate them all, if it's good writing I won't hate.
...and thats pretty much it
