Ore wa Warukunai (published as Don't Blame Me in English, by Juné IIRC) is the best of Yamada Yugi's work that I have read so far. I was introduced to Yamada-sensei while browsing through one stall's manga section at an anime con--I was intensely curious for the first time about Boys' Love--and one of the staff told me how accessible this book was, how it was about a film club, and so on and so forth. At first it didn't seem too interesting, like it would focus a lot on film-otaku banter and maybe some BL here and there.
Boy was I wrong.
This is a beautiful manga about growing up & thinking differently about friendship and love. It is a series that, even though it has only two volumes, should not be taken lightly--at all. That said, throughout there's still a wonderful humour, slapstick at times (Jun!) and subtle on the other (fighting in the school hallway, argh). You can have fun reading this. You should, because it's obvious that much love went into each page of this manga--it is easy to fall in love with the depth and the clarity of this world of filmmaking, college, part-time work, and failed sexual overtures.
These various threads of the plot are all given their own weight and presence, so that no one detracts from the other. Like one reviewer already mentioned, there are depictions of different types of relationships--queer or not--and each satisfies. Yamada here is amazingly able as a storyteller, flashing back, flashing forward, and switching lenses, keeping the suspense, all while introducing each character properly so you can really remember their name crystal clear! Plus, there are references to movie tropes, to gay-love-fandom-in-general (in the form of Miki), and even to the pettiness of the 'norm' of our homophobic, rich bourgeoisie.
And as for the sex? When the rest of the story is so very well-balanced, well-told, and well-drawn, the steamy parts get even more engrossing.
If you're thinking about it, just pick this manga up as soon as possible and see for yourself!!
