I think you should watch Shugo Chara
and Yu Yu hakusho
... and inuyasha... and tokyo magnitude 8.0.... and ouran high school host club.
shugo chara is a romance type thing but notrly. i loved it back then. yu yu hakusho is old, but its awesome. inuyasha is old too and i grew up with it so. tokyo magnitude 8.0 is SO GOOD. finally, ouran high school host club is really fun and addicting. its a romance and i garuntee you will love it.
another romance you will probs love is vampire knight. it has a second season called vampire knight guilty and is SO addicting.
happy watching! :D
