are there any well-animated romantic Аниме out?

Well, if Ты don't specify as to what shows Ты 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 Анимация for both is pretty good.

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

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