A new volume of Kono Oneesan wa Fiction desu!? comes out in July and I want to buy it, but ordering a single volume of manga on it's own is not a good deal. To make it worth it I need to order at least 3-4 volumes of manga. I do have a few series that I'm collecting in paper, but none of them (besides Kono Oneesan wa Fiction desu!?) has a release in July.

Basically I'm looking for some nice series that is preferably an innocent romance or some older female x younger male romance. The series should be 2-3 volumes long and without a scanlation (and probably RAWs too). As far as genres go, shounen, seinen or josei should be ok.

Please NO: hentai, shounen ai, shoujo ai
If it has ecchi, it shouldn't be very strong.

Since I'm going to buy it from a normal shop, the series shouldn't be older than a 3-4 years.

I have one backup series and I can order some volumes of it, but I don't really feel like doing so, so I'm asking for some alternatives here.

Raffmanga posts the raws as well as the summary of some manga. Some of the series they link are not translated, you can look through.
