animé suggestions please!

toi might get an idea about the kind of animé I'm looking for par lire the following examples..

AnoHana (pic)
Clannad
Angel Beats
Nagi no Asukara
Kokoro Connect
Sakurasou
Ano natsu
Little Busters
Sket dance
Chihayafuru
Chuunibyou... :P
Haruhi Suzumiya... XD
Free! ...maybe?

(the plot! the plot!!)

Technically, an animé that revolves around friendship... that is capable of bringing me on the verge of tears...
Also, those who've seen Mekakucity Actors, I l’amour the relationships between the members of Mekakushi Dan... So, something similar to it maybe...

NO sport! NO action! NO horror! NO ecchi!

It would be better if it's a short animé and please recommend animé that are worth watching only!
And please keep the 'list' short...

P.S. - just so toi know, I've watched almost ALL the mainstream romantic anime.. if u r planning to suggest any... and that's NOT what I'm looking for...
