Kouboku no Koi
Child psychologists and social workers who actually practice child psychology and social work within the story, which isn't half-bad. Conflict is added through a bit of family intrigue coming up from the past. Otherwise, a cute romance.
Toubou Kinshi!
Sakurai Ryou always draws such good looking men. She also specializes in stories where one of them represses his homosexual desires, for whatever reason, while the other is fully honest and open about his attraction, and not inhibited by sex in the slightest. This is a series of short stories that have to do with variations on that theme, and how these various men connect, not just physically, but emotionally. In the third story, the theme is stretched to include a (dog) spirit-male/human-male coupling.
Otona No Koi No Hajimekata

Nagase is clearly trying his best to seduce the prickly Shinougi, but so far to no avail. Presumeably this will change at some point.
