i advice u to watch Nana .. such a romantic slice of life anime but be ready for the tears there also: Itazura na kiss .. school life and after school life mix of romance & comedy Honey and clover is also good (there are 2 season & 2 ovas) .. hmm
paradise kiss is short (i guess 12 epi ) well .. i had seen alot of those anime .. i dont remember them right now...
