Maybe I'll try to contribute something to this thread this time. Let's see:
Hitorimi Haduki-san to. - a salarywoman who never had a boyfriend gets thrown into a relationship with a shy teenager; very hnng
Kyou no Yuiko-san - about a guy and his tsundere girlfriend; takes place in school
Renai Shimasen ka? - a guy who has a dislike of 3D woman, starts dating an attractive but awkward girl who works at a maid cafe
The Perfect Girlfriend - might fit, but only 1 chapter is translated
Tonari no Kashiwagi-san - should fit very well and it's quite good
Hadi Girl - a very awkward girl is forced into a relationship with a boy (vary innocent stuff); minor supernatural stuff happens though
Fantasy Maid - technically fantasy, but there are very little actual supernatural elements; has some smutty\mature scenes though; probably lacks comedy
Gotta second
14-sai no Koi, it's good.
There is an awesome series called
Futari no Renai Shoka which no one seems to be translating and which would otherwise fit the request.
If anime are ok too, you should definitelly watch
Chuunibyou demo Koi ga Shitai! and
Toradora! (or try them in manga\novel format).
And if you ever feel like reading shoujo, you could try this sugary shotacon named
Dear Mine
