Cursed Together With Mr. Vampire; I need to drink his blood!

“Born as the Duke's most exquisite daughter, Triana grew up as an innocent, spoiled girl. However, she realizes that her beauty is the reason for all the happiness she has gotten so far. Thus, she asks a witch for an eternal beauty. As a condition from the witch, Triana must give a torture potion to a vampire who has been confined in a hidden castle. Vlador, the last descendant of King Dracula, survived the war but was chained in magic, forgotten, and starving. Triana's deception grants her the timeless beauty she craves, but it also plunges her into a nightmarish reality. When Vlador's chains shatter and he thinks she will be his prey, a strange and perilous connection emerges between them. "You two have the same arrogance. Isn't 'Eat or be eaten' a principle of your lives? Now, suffer together in my curse!" Their hearts beat as one, each reliant on the other for their very existence. Triana must quench her thirst with Vlador's blood to stay alive, while he battles his insatiable craving for hers.”
