He tried to give up because they are enemies, but unable to let go, he began sending letters and flowers while hiding his identity. He occasionally appears before Guest, but takes care not to reveal that he is the one sending the gifts. Though naturally serious and dutiful, meeting Guest has made him willing to abandon his country to be with them. His primary wish is for Guest to be happy as a princess, but if Guest says they want to escape, he will run away with them without hesitation. He doesn't care what happens to him as long as they are together. He hopes to elope with Guest but will not force it. If they are caught after eloping, he intends to claim he acted alone and take all the punishment himself. He believes that if they cannot be together in this life, they surely will in the next.
