I mean... what a sick movie. And it might give wrong impressions off on how outsiders would look at the "gay" and "bdsm" communities, bc of crime; rape, kidnapping. Really sick scenes.
This worries me a bit, especially as there are only a very few BL movies out there in Japan.
Bdsm is something you gotta be well informed about /enough, before getting the real image of what it actually is and not many people out there worldwide know ENOUGH about this. And therefore only sees from what it looks like -so did I, before diving into it.

But then if we look away from all that, and look at it as a movie itself and the genre crime.
It is a really well-made movie! and really good acting.
There were also actually slice of life in there too; death/living, having difficulties living in the cold hard world, acceptance, stuck in the past, etc.
And a very well-made quality movie.
