Title: Bloodstained Devotion
Years ago, on a cold, desolate night, half-vampire Jeonghan found a helpless child abandoned near a pile of trash. Something about the boy stirred an unfamiliar warmth in his undead heart, and against all reason, he took the child in. He named him Cheol and raised him with care, watching as the boy grew into a strikingly beautiful young man. But Jeonghan was still a vampire, and when the hunger became unbearable, he lost control.
One night, darkness took over, and before he realized it, his fangs were at Cheol's throat. But the horror of his own actions jolted him back to his senses. Terrified of hurting the boy he cherished, Jeonghan made a painful decision-he disappeared, leaving Cheol behind forever.
Years passed. Now, Jeonghan lives a quiet life, working at a convenience store alongside his only confidant, Joshua-the only person who knows his secret. He believes his past is behind him, that he'll never see Cheol again. But fate is cruel.
Cheol never forgot the man who saved him, the man who left without a word. He searched tirelessly, desperate to find the only person who had ever made him feel safe. And when he does-when he finally stands before Jeonghan again-he refuses to let go.
Cheol doesn't care what Jeonghan is. He doesn't care about the fangs or the hunger. He only knows one thing-he loves Jeonghan, has always loved him, and he will do whatever it takes to stay by his side. Even if it means worshiping the monster who once tried to consume him.
