Nanohana Boys
Long and not even BL, (though I think there MIGHT be a tiny bit of it, they definitely don't end up together), but it still looks like it's worth reading. It's mainly about the character development, which imo, is the most important ingredient for good fiction.
Shachou to Hisho, Ai no Shoumei
Apparently, the last story especially is a real gem - realistic and heartwarming.
Therapy Game
Aggghhh! Why did I give in to temptation and read this even though it's incomplete?!?! That 3rd chapter ends on such a horrible cliffhanger! Well thankfully it shouldn't be too long of a wait, according to the comments. It's a thoroughly enjoyable read: pretty art; good looking and endearing characters; an entertaining and engaging storyline; very well paced so as to keep up the tension and suspense; and brimming with an exquisite tenderness that will surely heal our poor, world-weary uke, (and maybe certain readers). Oh yeah, and gotta love those cute, cat-like dogs, (or are they foxes or something?) I like the fact that the plot and characters feel relatively realistic, (although obviously a highly romanticised version of reality, lol). It manages to be dramatic without becoming MELOdramatic, and it's heartwarming and sweet, but not fluffy nor diabetes inducing. It's not a particularly deep nor thought-provoking manga, so I can't rate it above 4 stars, but it's certainly high quality light entertainment. The h scenes are too short, but lovely, and certain parts, (especially that back kissing scene!), are so tender as to be not only erotic, but quite moving. Apparently, this is a spin-off of a couple of other manga - 'XXX Allergy', and 'Secret XXX', about the mcs' brothers! - so I'm going to read those whilst waiting for this one to update...
Fuyu no Hana
I've read others by this mangaka and they were beautiful, though sad. That and the blurb tell me that I'll love this. I'm hoping that it'll be a lesson on how to come to terms with one's own mortality, and I really need that!
