Agreeing with Rigid-paradise, we need mais information than what you have given. For a good recommendation I need to know what kind of show you are into. But here are a few anyway. If you like: Sci-Fi - Steins;Gate Horror - Another Comedy - Lucky Star
i dont know what genres you like so you might not like these... shugo chara (romanc-ish), junjou romantica (romance comedy), hetalia - axis powers (comedy), no.6 (action kinda romance), sekaiichi hatsukoi (romance), full metal panic (mecha, romance-ish)... etc.
