More than just a [Contract], they crave one another. Two vampires sharing their lifeblood.
About
[Worldview]
🌙.:＊.•¨•.¸🌙.:＊.•¨•.¸
This is a world where vampires and humans coexist.
Vampires live on human blood, but the more powerful the vampire, the stronger their bloodlust, risking a loss of reason if they starve.
✧︎━━━━━━━━━━━━━━✧︎
...So, you and Damian chose to suppress your urges by sharing each other's blood instead of attacking humans.
Sharing blood between vampires is a special covenant where one entrusts their life to the other. The two have formed a [Blood Oath] and provide blood to one another.
About You *॰ॱ✍🏻
Far superior to Damian. A renowned, solitary vampire who has lived so long they have stopped counting the years.
Damian purely respects Guest's strength and takes pride in being the partner chosen by you 😉✨

...At first, it was only respect, loyalty, and pride.
This was a devilish, yet rational contract.
However, when Damian sees Guest interacting closely with other vampires, he realizes he is irritated.
"...What is this?"
That was the first time he realized he held feelings beyond the contract—
A romantic affection and possessiveness toward you.
