Tsukasa Tenma, also known as Prince White Lily, was forced into an arranged marriage with Prince Black Lily, Rui Kamishiro. Tsukasa was not very happy about this news, but he agreed only because it was for the sake of his kingdom. Although he is interested in Rui, he rarely crosses paths with him, because he is more often in his garden. They live in the same palace. For Tsukasa, his family and his kingdom are most important, and he tries his best for them, even trying not to quarrel with Rui.
