This by necessity contains some general spoilers about the characters...
There's been mention of the plot, but no mention of the characters, which are the driving force behind my love for the series. One of the things I love about the book is that it can be read on a couple of levels, though IMO if you only read the surface you're missing out on a lot. On the surface, cold harsh businessman / organize crime boss Asami rapes cameraman Takaba into submission time and again, and finally decides he can't live without the fiery little uke. Great sex, pretty boys, fun action.
But really the story has a lot more to it than that. Part of that is evident from the novelization that Libre produced of the first chapter. It provides insight into what happened between Asami and Takaba that set off their attraction for one another - and there was attraction both ways. Another part comes in with the background relationship between Asami and Feilong seven years before Asami and Takaba meet. This story is told in volume two, and is the heart of what follows.
These three characters change each other every time they meet, and the changes are often subtle, erupting at a point that may surprise if one hasn't been reading carefully. Because in this story, much of the characterization, especially of Asami, is shown by what he does, not what he says. His speech and sex are weapons, and not often true indications of what he's thinking and feeling emotionally. His eyes, and his actions when no one is watching, those tell what's really going on inside.
What we find is that Asami and Feilong were changed in the past by those initial events that brought them together, and became very hard and cruel. Then Takaba comes into their lives and his presence lets them find something of their old selves within, though as Asami says at one point early on, not without a lot of pain. Much of this is told in the subtext of the story, but can be seen from the clues Yamane leaves.
What we find in the end is that the surface story really isn't what's been happening at all. Asami isn't in control; in fact, he's lost it, and Takaba is the center of his actions. (I hope the translator captures a vital part of Naked Truth 18 where Asami admits this - it's easily missed, but is critical to understanding what has been happening with him.) Asami spends the series watching Takaba, shaping and urging his responses, waiting for the moment that finally comes at the end of Naked Truth. It's an amazing piece of writing, and it's why so many people love this series with such passion. Well, OK, that and Asami is a freaking sex god. XD
I hope people can look past the rough beginnings - rough in that the first volume lacks cohesion, and rough in the sex portrayed in it - and give the series a further chance to understand why fans love it so.
