Whew... this one hurted. There is a lot of smut, but there's so much angst behind it as well. Nanao gives off the usual resilient strength that we see from people being forced into these situations, but underneath he's so fragile and just wants love. Soushi is so similar in that he wants love, but doesn't ever pursue it because he's afraid of succumbing to the Alpha nature that seems so commonplace in their society. But they find each other, and get a happy ending.
