Basically, you want a romance story that plays in a realistic environment (since Nozoki Ana is not really "realistic" )
Try these:Bonnouji
Horimiya
Koe no Katachi
Molester Man
Beck
Otoyomegatari
Emma
Our happy hours
Solanin
Nana to Kaoru
Stuff by Adachi Mitsuru
Onani Master Kurosawa
Sekitou Elergy
Haru yo Koi
Koibito Play
Velvet Kiss
Glass no Megami
Sundome
Honeymoon Salad
Densha Otoko
and stuff by Kitazaki Taku
Thanks for the suggestions, I'll check them out =)
Also the "reallistic environment - this one isn't a "must" have =)
If the rest is good, I'll check it out too (like Nozoki Ana^^).
