Hi, here's the list of BL (Boys' Love) dramas and movies. Unfortunately, there are not many BL Japanese dramas out there, but feel free to mention any BL dramas or films you can think of so I can add them to the list!
*NOTE: all of these dramas' main plots revolve around BL unless stated otherwise!
Huh, I honestly don't remember RH Plus actually going the BL route (hints of it, teasing at it, yes, but no delivery). Not sure about the manga though.
Anyway were you looking for dramas specifically based on BL manga? Or just anything with a male-male romance? And if you're counting RH Plus, what about other shows heavy on the subtext (but no explicit delivery)?
I would suggest Aozora no Tamago-- not explicitly BL but the subtext is pretty heavy (Tori & Sakaki are *very* devoted to one another, though if you want to see them as just very close friends you can). I think this would fit the "obvious that it's aimed at BL audience" criteria.
Also-- and this is kind of a minor spoiler for the first part of the show, but you're looking for this content so I'll say it anyway-- in the 2006 drama Dare Yori mo Mama wo Aisu, the oldest son Akira realizes he's gay and eventually starts a relationship with another man. It's not a perfect representation by any means; Pinko starts out as a gay stereotype, very flamboyant and rather pushy about his interest in Akira. But the show does develop him beyond this caricature and we get to see him as a more fully-rounded character. And his interaction with the rest of Akira's family is so good too (this is seriously one of my favorite family dramas, not just for the Akira/Pinko storyline either).
