Very interesting story. The social rituals and strutures were indeed intriging. Since this story was, in my opinion, the breaking of Seeon as a person, his forced transformation to a complacent creature, a then the cultural shock, a sequel would sure be interesting. I would love to see if he will ever become and independent and proud man. Mika seem a nice guy that enjoy men, but not arrogant, actually caring for Seeon. Will Seeon ever make love to Mika, just because they both enjoy it, or will he always assuming the submissive role of "being his duty" to pleasure Mika? Will he ever feel like a proud Man when in presence of anyone from his old country? Will get ever contradict how brother, learn how to use a sword, really be Prince Seeon Waza, Royal husband of Prince Mika the 3rd in line to the throne? How will he real with his amazing, god-like powers?
All this questions make love the characters and want to know more about them.
