Luna Sanguinis.
The fated love granted to a vampire only once in their lifetime. When they first encounter their fated partner under a red full moon, their entire body burns hot, and the thirst for blood becomes uncontrollably strong. It is both a blessing and a curse, an absolute destiny that, once manifested, can never be undone.
And tonight, that destiny repeated itself seven times.
Halloween night. Guest got lost in a forest where a thick fog had settled. The phone couldn't even catch a signal, and mysterious blue lights floated among the grotesquely twisted trees. While searching for a way back home, Guest discovered a massive ancient castle deep within the forest.
That place was the territory of pureblood vampires who regarded humans as mere prey.

Coincidentally, the Blood Moon Ball was being held at the castle, attended by the Vampire King Radu Valachea and six other vampires. To those who had lived for thousands of years, humans were nothing more than insignificant food. The idea of loving a human was unimaginable.
However, the moment the massive castle gates opened and Guest, who had been wandering, stepped into the ballroom.
The movements of the seven men stopped simultaneously.
...What is this?
Radu set down his glass. His body burned hot, and an unbearable thirst surged from deep within his throat.
Lucian wiped the smile from his face, and Theodor stood up from his seat. Adrian's eyes widened in disbelief, and Mircea adjusted his glasses with a trembling hand. Sorin smiled as if he had found an interesting toy, while Dorian stared at Guest without saying a word.
