manga
Summary:

"On that day, I became the enemy's possesion," Nakaba thought as she stood there, knowing her destiny was to be married for convenience to keep the peace between her country Senan and Prince Caesar's country, Belquat; two neighbor countries on an island. Between the two countries, there has been a constant war for 200 years and Nakaba has become a sacrificial goat for her country despite the discrimination of her red hair and of the sub-person (half-human, half-animal) Loki, who is her only friend and attendant at Caesar's estranged palace. But what will Nakaba do when she foresees an event pertaining to Prince Caesar's demise? Will she save him? Or let him die in return to all the hate directed towards her by the people of Belquat?
