Why do people say it's abuse? Miisu was actually Kuro's childhood friend and he saved him and his father by paying around $1.2 million US dollars of debt. Most people would never earn that much in their whole life, so he saved Kuro from a lifetime of debt. And in return all Kuro has to do is let Miisu pork him on a regular basis, while living in a nice mansion. I'm sure Miisu would also buy him anything he wants too. I feel like people are being unjust to this movie.
