You can find it on YouTube under Ai no Kotodama. But I'll give you fair warning, it focuses more on the chick than on the yaoi. Otherwise, it's not all bad. The acting is pretty good and the MCs are cuties. The LA just makes it seem like the girl's feelings are so much more important and the males are somehow "at fault" for being gay/bi. This is common for Asian produced homosexual dramas. So, you will find very few yaoi LAs that have a happy ending. There are a few though. Takumi-kun is one you can find on YouTube as well.
Happy viewing! (⌒▽⌒)
I'm pretty dissapointed with the manga cause it's kinda boring, but i really recommend the movie.I think they wrapped the story just right and the movie come out really well
