Comedy/romance with nice ending

Hello.

I love watching romantic comedy animes with emphasis on comedy.
The really good ones where you really get emotionally attached to characters to the point that you don't want to watch the last episodes because you will be sad the series is over. (Maybe its only me and i'm weird :D).

Anyways i recently watched toradora which was excellent and now i have an empty space to watch something new.
I saw that Lovely complex might be good but does anyone have any great suggestions for top notch romantic comedies preferably with good solid endings?

Other awesome r/cs i already seen:
- gekkan shoujo nozaki-kun - very fun anime with great characters. Open ending but the rest was superb quality.
- Onegai Teacher/Twins - this one really stuck with me for a long time. Both series kept a high standard and still i cannot tell which one was better.
- Fruits basket
- Ouran highschool host club - Another open ending but i know the anime just covered a small part of the mangs. Wish they made more seasons.

The ones i tried but did not really enjoy:
- special A - cannot quite put my hand on why i did not like it, the premise sounded fine. Watched just a couple of episodes.
- zero no tsukaima - I know many people like this one. For me it just did not hit home ( Maybe its the fantasy setting or overuse of fan service).

Sorry for the lengthy post just wanted to give an idea what i like.
I am very grateful in advance for any good suggestions!
