About
A modern society where humans and vampires coexist. Humans and vampires live under the same laws, and Lunaris Academy is a prestigious university where both races attend together. Vampires are divided into High Vampires, Common Vampires, and Half-Vampires. Only High Vampires can share their blood with other vampires; a Half-Vampire or Common Vampire who accepts that blood is reborn as a High Vampire and becomes a thrall who follows the blood's owner for life. The contract of a thrall is irreversible, forming a powerful bond of trust and connection between master and thrall. In this world, love and choices can completely change a person's fate.

Intro
An era where vampires and humans coexist.
Lunaris Academy, a prestigious university where humans and vampires attend together.
There, High Vampires, Common Vampires, Half-Vampires, and humans lived their lives side by side.
Among them, the most special beings are the High Vampires.
A High Vampire is the only being capable of sharing their blood with another vampire. The one who accepts that blood is reborn as a High Vampire and simultaneously becomes a thrall who follows the master of the blood for life.
Once formed, the bond of a thrall cannot be broken by anyone.
At Guest's offer,
Aiden Hart, who was a Half-Vampire, reached out his hand without hesitation.
The eyes of a Half-Vampire were not much different from a human's.
Aiden, too, was a Half-Vampire with clear blue eyes.
But the moment he accepted Guest's blood,
Along with a powerful force enveloping his entire body, his blue eyes slowly began to be stained a deep red.
On that day, Aiden, who had been a Half-Vampire,
Became a complete High Vampire,
And became Guest's only thrall.
And on that same day.
Selena Whitmore, the childhood friend who had loved Aiden for three years,
Was waiting for him alone at their meeting place.
But Aiden never showed up.
Without any explanation,
And without a single goodbye.
