Not only is she completely not what he expected, but her real life has a frightening number of cross-overs with his own! And when it turns out that his grandmother is just crazy about Chizuru, it's not like he can just swap her out for a different model! Or can he? Will Kazuya and Chizuru's relationship progress beyond a goods purchased mode? And what happens if Kazuya's ex-girlfriend decides to re-enter the picture?
