愛の言霊 (Ai no Kotodama; Words of Devotion) is a Japanese Boys Love movie that was released in 2008.
Story: Shinya Ootani and Miyako Tachibana have been best friends since high school and started living together about two years ago. Actually the two of them are a quite cute couple but one day Yuki, a friend from high school, shows up and Ootani starts feeling jealous and somehow insecure.
The movie shows the life of a gay couple and no one around them knows that they actually are a couple and not only close friends.
Cast: Yasuka Saito as Miyako Tachibana has acted in a few other boys love movies before so I think his acting in this field is pretty solid. It's not like I could really complain about it.
After all the chemistry between the two leads was good and their acting was nice to watch.
My personal rating of this movie is 6/10 though. The movie isn't bad but since I'd say it's rather about a couple's life (and it doesn't even matter if it's a gay or straight couple) with a nice ending but a not-so-deep plot. It's not that exciting though it is a sweet story finally not about how people start dating but their relationship itself.
