This is one of those manga that is so flat and dull you're left wondering at the end "Why did I even bother?"
Admittedly, it is about 90% realistic; and lacks the contrived, sugar-coated fake happy endings that plague the BL of today...but honestly, I've never come to appreciate the absence of realism in conventional shounen-ai manga more than when I was reading this.
Nemureru Mori no Binan is not particularly deep or touching - nor is it funny or witty. It resembles a homosexual-themed, much less skilfully-written version of Asano Inio's manga - featuring very believable characters and their 'real adult' life-styles which succeed in doing nothing more than putting me to sleep.
A little surrealism is important for any story; since if fiction was so realistic...well...it wouldn't be fiction anymore, now would it?
And both protagonists are - to put it simply - hateful. Richard is the worst kind of pervert - he thinks cheating on his partner is natural, and feels no remorse whatsoever regarding his actions. When the AIDS issue came to light, my guess is that we were supposed to feel at least slightly sympathetic. But I only found myself thinking; "Serves him right, that slutty ba****d!"
Tomoi, on the other hand, is an arrogant, annoying and thoroughly immature man - making it impossible to feel for him, even in light of the obvious hardships he has been through.
I've encountered characters with much greater flaws than these two (like, say, Nakoshi and Ito from Homunculus) and have understood and appreciated their three-dimensional personalities; but Akisato Wakuni obviously does not possess Yamamoto Hideo's skills as a writer.
If you're looking for a realistic shounen-ai manga that is so much more thoughtful, likable and funny - following the lives of characters you can actually sympathize with and care about, try Kinou Nani Tabeta? Don't waste your time on this.
^To the the gentleman called kevintheman: I'm "refusing to respect people’s freedom to read and do what they want"? When and how did I do that? I'm criticising the characters in this story and critiquing the mangaka's writing style from my personal point of view -- which is what this section is for. I did not target any real people, consumers of this site or otherwise, except in the general "do/don't read this" sense that everyone else does. You're the one who can't seem to make a comment without casting aspersions on another commenter's views (and character!) in the process. But I apologise if something I wrote inadvertently insulted your lifestyle; that was not my intention.
