MistukixEichi (I think this counts) from Full Moon Wo Sagashite
These two are always so sweet together! And he is so kind to her!

KagomexInuyasha from Inuyasha
Love the funny relationship they have, and I love how neither of them has more power in the relationship

HachixTakumi from Nana
I have no idea why I like them; Takumi is such a possessive jerk! But I guess I like how she knows he's bad news and she doesn't try to deny it, to him or anyone else. And I think Takumi would make a great dad.

KaoruxKenshin from Rurouni Kenshin
So sweet! Love both characters, and I love them both together.

YuukixKaname from Vampire Knight
I just like this one. Not sure why.

HanaxVivi from Hana to Akuma
So cute, once you can get past the pedophilia (I mean, I know he's a demon, but he's known her since she was an infant! And she's only 14!)

LucyxLoki from Fairy Tail
I love how happy they always are together. And I love that even though Natsu and Lucy are the main characters, Loki and Lucy are the canon relationship. And Lucy's just fun.

TeruxKurosaki from Dengeki Daisy
I love how jokingly mean they are to each other. And I love how they treat each other as equals, despite the age difference.

Lol, have you actually read Fairy Tail? Besides that fact that there aren't any canon relationships (as of yet) Lucy and Loki are the farthest thing from canon.
