if u want cuteness, K-ON is a MUST. its pure cuteness
dont underestimate this anime for the "Music" tag, u will fall in love for one of these girls
Chuunibyou demo Koi ga Shitai! is cute too but with some plot
and if u want some weird romance with a tsundere loli, Toradora is one of those animes that if u are talking with another anime/manga fan and u say "who's Taiga" he will lose all the respect for you.
