are there any well-animated romantic animé out?

Well, if toi don't specify as to what shows toi seen, it's somewhat difficult to know we're not posting one you've seen. I'll just recommend Toradora...

i think Kimi ni Todoke is really good :3

Suzuka is a romantic comedy shonen anime/manga. Its about a guy whose romantic interest is on the track team. It's one of the few romance shows for guys that doesn't devolve into a harem. Some other ones I can think of that actually involve a steady relationship are Ah! My Goddess, Ai Yori Aoshi, and Psychic Academy.

Clannad

try sukitte ii na yo and tonari no kaibustu-kun!! they're both really good and have cute art styles; the animation for both is pretty good.

Acchi Kocchi is a really good one that just came out this an :3

toi need to watch Sukitte Ii Na Yo. Right now. It's amazing and so is the animation.
