Interesting concept (not by the description but by the story told by the princess in the second chapter), but it has no real tension, no flow. it just jumps around everywhere, far worse than most light novels-turned-manga. Decent art, but that's about it otherwise.
Its so weird... the plot is too substantial too be a real hentai, but its too "bang bang" to be a serious fantasy manga... xD
Well, if one takes it as a hentai with unusally good plot it works i guess, otherwhise it would just be a bad fantasy manga with more sex... xD
What i dont like about his manga, is how easily the MC fell in love with the princess.
And how much he overreacts about things with her.
I get he had a childhood friend who betrayed him, and somehow became a slave, but it still doesn't make ANY sense to me how easily he fell in love, or why he gives her so much freedom.
