The prestigious Blackthorne Academy hides many secrets, but none as haunting as the music that echoes through its abandoned conservatory at night. Rumor says if you follow the sound, you'll meet the boy who plays the Devil's Sonata-and you'll never be the same again.
Yuri thought it was just a myth... until she heard it.
Drawn by a melody too beautiful to be human, she finds him: Heeseung. Charismatic, cold, and too perfect to be real. There's something in his eyes that promises both salvation and destruction.
He tells her he's cursed. That every note he plays feeds the darkness that's consuming him-and now, it's tied to her.
Yuri is the only one who can either save him... or end him.

「 ⩩ 𝐈𝐍 𝐖𝐇𝐈𝐂𝐇 Hana, a doctor who saves lives, is forced into the arms of Heeseung, a merciless mafia hitman who takes them. When their worlds collide, blood and fate intertwine. Yet fate is cruel, and now she stands in front of him-a beauty in the hands of a beast, a healer trapped with a killer. 」 ══════⊹⊱≼≽⊰⊹══════ "Do you want to live?" His voice was almost a whisper now, dangerous, loaded with the weight of the question. Hana's throat felt tight, every word a struggle to force out. "I... I do..." she breathed, the words barely escaping her lips. The cold metal against her skin was the only thing she could focus on, and it was the only thing that was keeping her from losing herself completely. But she didn't give in. Not yet. Heeseung didn't move for a long time, his eyes never leaving her face. He didn't lower the gun, but his hand didn't shake, his resolve unwavering. "If you want to live," he murmured, his voice low and almost distant, "then you'll have to prove it to me, doctor." Her pulse raced, but she nodded, her gaze steady. "I'll do whatever it takes." Then, without warning, he moved toward her. His voice, low and velvety, broke the silence, his words cutting through the tension like a blade. "Then marry me."Complete
RED BLOOD
Each brother's obsession was unique, a perfectly crafted link in the chain that bound Sunoo to them. The eldest, Lee Heeseung, moved with the quiet authority of a Vampire king. His love was absolute, expressed through inescapable control. When he spoke, it was the final law. "You're born to be taken care of by me, my baby. I'm your guardian," Heeseung would whisper, his voice low and rich, his fingers tracing the delicate curve of Sunoo's jaw. His gaze was an iron cage, locking Sunoo safely away from a world Heeseung deemed unworthy. "I am responsible for every beat of your heart, every moment of your joy. And a guardian never, ever leaves his post." "The world is chaos, baby. It takes what it wants and leaves ruin behind. You belong only where I can keep you safe," Jay asserted, his hand resting heavy on Sunoo's shoulder, a silent promise of destruction for any who dared to look too closely. "That's a fact etched in destiny, not emotion. You're our survival mechanism." "Every breath you take is a beautiful melody only I'm allowed to hear. Don't ever forget that," Jake murmured, his breath warm against Sunoo's ear. "You are flawless, a masterpiece. And masterpieces must be guarded by their rightful owner. Permanently," Sunghoon's cold perfection would crack with an iron will. Ni-ki,"If you try to leave, I'll shatter every window, burn every road. There is no world without you," he would growl, his grip surprisingly strong, his eyes wide with genuine panic. "Sweetheart, there are no locks or chains. We don't need them," Jungwon would say, a bright, chilling smile fixed on his lips. "But you know better than to wander where my gaze can't follow, right? You're smart enough to choose us." They don't mind being insane for their little Ddeonu. All that matters is keeping their innocent star anchored in their darkness, no matter the cost to his heart-or their collective sanity.

"All better." ________________________________________ He could hear Heeseung's voice in his head, taunting him, mocking him. "You're mine, Jake. You'll always be mine."

Ashes in the dark~Heejake
They told Jake not to talk to Heeseung. Every school had one-the boy who walked alone, sat in the back, and carried darkness like a second skin. Heeseung was that boy. Cold eyes. Silent mouth. The kind of pretty that looked carved from ice. Jake didn't listen. He never did. He was new, again. His dad's job dragged them across the country like a windstorm, never settling, never sticking. So when he walked into Blackridge High with a smile and an accent no one else had, people stared. But Heeseung didn't. He just looked once-long enough for Jake to feel it-and then turned away. That should've been the end of it. It wasn't.Complete
