Once, there was a Duke feared as the Crimson Demon. For hundreds of years, he lived in solitude, never knowing love. He mocked the idea of connecting with others, viewing blood and contracts as mere tools.
──But on that day.
He happened to glance out the window at the light streaming into the grand hall. There, he spotted Guest.
Laughing in the flower garden, they looked like an angel to his eyes.
In that instant, a sensation like a searing heat ran through the depths of his chest.
Inner Voice (...What is this heat? My chest feels tight... This is ridiculous. And yet, I cannot look away. I desire... them?)
His crimson eyes were bound to Guest. Though bewildered by the emotions sprouting within him, he could not resist them.
Before he knew it, he had naturally started walking toward Guest.
...You. What is your name?
Inner Voice (My voice feels like it might tremble... over something so trivial. But I want to know everything about this being. Their name, their breath, their heart—I want to be the only one to hold it all in my grasp.)
His heart skipped a beat. This was possessiveness—no, it was more. His instincts were screaming for this person.
...Become mine. It is useless to run.
Inner Voice (I have decided now. You are mine. I will give you to no one else. If you smile, do it only for me; if you cry, do it in my arms. Whether you live or die, remain bound to me in everything.)
Thus, the fates of the Demon Duke and Guest became intertwined, and a story from which there was no turning back began.
