He died killing the Demon King. He woke up sixty years too early. Now the monster is a young man. And he is running out of reasons to stay away. --- Lysan Dusk was the hero who saved humanity. He killed the Demon King, ended the war, and delivered the world from suffering, and his reward was betrayal. He wakes up in a young student's body in a dormitory room of a magical academy, and the calender shows that the date sixty years before he was born. The world outside hasn't broken yet. The war hasn't happened. Lysan's plan is to keep it that way by staying completely out of it. Fail his combat exams, spend whatever borrowed time he has left, living a quiet life, where nothing requires him to be a hero. The man who will become the Demon King, the most feared monster in history is still young and beautiful, with pale grey eyes that find Lysan across every crowded room like he is the only person worth seeing. Lysan knows what those eyes will become. He has looked into them across battlefields, spent a lifetime seeing them in nightmares. He never expected it to feel like this up close. Roman is everything Lysan was warned about — magnetic, dangerous, impossible to ignore. Everyone except Lysan, refuses to be charmed, refuses to feel anything at all. But now, he is failing spectacularly at them because Roman keeps finding him. Keeps watching him and making Lysan's carefully rebuilt walls feel like paper. Lysan knows the ending. But for the first time in two lifetimes, he is wondering if the ending can change. If the monster can be loved instead of killed. If staying is braver than running.

"I curse you." A mewled whisper erupted her throat steadily raising her shaken up gaze. The man who had her jaw held in a terrific grip gave her a twisted smile having no effect from her words. He found them absurd and full of stupidity. "I CURSE YOU! YOU AND YOUR FATHER WILL LOSE ALL YOUR HAPPINESS AND PEACE! IT'S A CURSE OF A DAUGHTER, YOU IMBECILE!" She cried loudly right on his face which did snatch his smile but something in him refused to accept the power behind her curse. But her heart bled curse did what he considered a myth. Shaken up his soul. Tarnished his peace. Snatched his every happiness. He was left with nothing but agony and pain he once conflicted on an innocent. If you want to read a story full of regret, redemption, hate and pain then welcome. WARNING: THERE CAN BE GRAMMATICAL MISTAKES SO DON'T MIND.

She accidentally summoned the great Demon King but all she ever wanted was to get rid of her ghosts. “Can I take it back?” She asked, blinking innocently with her soft long eyelashes. “You’ve sealed the contract with the kiss. There’s no going back now.” A smirk played at his plump red lips.

Prologue “We can’t be together,” he whispered, voice breaking. “You are my destruction.” Tears burned her eyes as she shook her head, stepping closer even though it felt like standing at the edge of a blade. “And you… are my ruin too.” The words tasted like a goodbye neither of them could accept. They were bound by something older than choice, older than mercy. A curse carved into blood and grief, waiting patiently for the moment they would finally meet. They were never meant to love safely. And if they ever surrendered to it— One would die. The other would be destroyed by love. The curse waited patiently. And destiny, cruel and inevitable, had already begun to pull them closer.

Arianna had not planned on using magic to summon anything, she just wanted to get out of an arranged marriage. She was told of the ancient magic of summoning a guardian but instead she had summoned a demon—the demon king himself. But what would he ask in return for his loyalty to this princess?
