Summary
Prior to her current life, Emu was a knight. She had been sent to try and liberate captives and vampires from a dictatorship in the Vampire Clan. And she and her companion and fellow knight of sorts got captured as well. Most of all, she fell for the heir to the Vampire Clan throne as their thrall, and died trying to get them both out of the kingdom.
Now, she was alive again. It was a vastly different situation, being a knight in the Intema Kingdom with eyes on the current ruler. Especially with Lord Kanade having returned affection. And even more with knowing her last life as if it was just yesterday, and having to pretend she doesn't know the vampires as they visit.
When Mafuyu returns into her life, knowing it's her? A sudden change happens and Emu is left to navigate how to handle being romanced by two people.
