Ouji No Hakoniwa

Once a rich young master, Yuzuru hit rock bottom after his family went bankrupt. That was eight years ago. The butler who took care of him, Iwase, has since risen to the top. When Yuzuru learns of this, he returns in an attempt to make some quick cash. But Iwase sees a kid who is still his charge. He captures Yuzuru and locks the young master in what was once his own home. Now, Yuzuru must use every trick in the book to make Iwase realize that things have changed, that he is no longer the innocent child from years ago.
