Koitomo!?
Spin-off of 'Katekyo!' The couple appears in this chapter: http://www.mangago.me/read-manga/katekyo/mw/c015/pg-5/ 3.5 stars. Adorable! One could say that they tame each other. Haruka is such a caring seme, despite his forceful nature. Beautifully drawn of course. I prefer 'Katekyo', in which the mcs are more fleshed out, but this is good too, although not a masterpiece.
Hisho No Territory
Apparently, this is a sequel to 'Crystal Harem', but from the summary it doesn't seem so. I guess one of the stories is the sequel, but not the others.
Koi o Suru nara Kono Machi de
This sounds interesting! After this, read the spin-off 'Kizutsuite Romance'.
Nez
A detective with an extremely sensitive sense of smell plus rhinitis! LOL sounds too much like someone I know - I need to read this!!
Rinjin wo Aisou
