This was done incredibly well. It was about debts and prostitution, which is a fairly common topic, but it was done in such a new and refreshing way. I feel like the relationship between Shiro and Kei should've been developed a bit more deeply, but I loved the plot and the side characters. I wish we saw even more of Shiro, since his backstory is amazingly tragic. All in all it's a very good story.
