There's definitely some missing chapters and I think that a one shot was plugged in that shouldn't be there. While that used to be common in manga published around this time, this one seems completely out of place and there's definitely some missing pieces because the author's note goes into inside jokes that aren't applicable to any chapter uploaded so far. Although it's an old trope, I did want to see the prince chase Suzuki to Japan.
Started strong with a good tragic slave plot...but then after the climax if the story it just got muddled. The resolution doesnt have nearly as much development as the other parts and doesn't feel like part of the story.
