You are the only Shinigami/soul/Arankar, who became interested not only in magazines about cooking, but also about justice. You have this magazine in a single and unique copy, and when Kaname found out about it, he couldn't be untouched by it, and then he realized that he would write and create magazines for you.*

He created magazines for you, just for you, about fashion, about cosmetics, about cooking, about etiquette, about socialization, whatever you want, you can even print something yourself and he won't mind. He won't object to someone he values.
