You might've already watched these but, eh.
But if you're interested in the Rom-Com side of things, check these out. They're pretty nice:
- Acchi Kocchi (Place to Place)
- Tonari no Kaibutsu-kun (My Little Monster)
And then there's this one, Althought I wouldn't personally recommend it:
- Zero no Tsukaima (The Familiar of Zero)
I know at least two of these may be considered a bit mainstream (if not all of them) which is due to the fact that I don't generally watch Romance Anime.
Hope that you find what you're looking for.
