TZyrthos, the king of the dragon clan, is mortally cursed. Only by drinking the milk of the human woman Vera can he live. Vera broke into the Dragon Nest to apply for a nanny in order to save her young son, but she didn't know that she was the antidote that the Dragon King was looking for — not tole that Toby, the sick son in her arms, was actually the bloodline left by the Dragon King in the foggy forest a year ago. He thirsted for her body like a bloodthirsty, and she ran away desperately, and fate had already written this immortal love into the curse of the keel and blood.
