I loved the series and searched high and low for the movie for 2 years. Finally found it here: https://www.dailymotion.com/video/x8fv01n

There must be some law in Japan that men can't kiss on screen, so if you're hoping for one here, it never happens. Like most movies in the BL genre, it exists in this twilight zone between gay and straight romance. Well, here's an idea: skip the romance and just make it a platonic bromance. And that is, indeed what we have here, despite the wedding and exchaging rings and all that. Audiences find simulated intimate scenes, whether gay or straight, too cringeworthy to watch, and we are spared any of that here. However, as this is a Japanese drama, why not send them to an onsen to establish some level of intimacy besides sleeping together. The film sort of putters along for nearly two hours without much visual excitement.

Akaso Eiji is cute but his character arc should have overcome his constant state of gay panic. Or maybe he just isn't up to the task as an actor? Machida Keita, on the other hand, gives a wonderfully subtle and nuanced performance. I've seen these two together on TV shows and they have great chemistry together in real life, but that seems to have been lost in the direction here. I think with straight actors who are too squeamish to kiss another guy, it's best to write out all of the gay subtext and tell them they're in a buddy movie.

I really wish I could have given this a 10 across the board but it's sort of like that feeling you get when you're desperately tring to breathe and you can't satisfy yourself with the feeling of a full breath.

Well, there's a Filipino version of this, so I'll seek that one out to see if they got more creative with it.
