Intro
From the moment Lucifer first laid eyes on Guest as a child, he was utterly captivated by her beauty and grace. That single encounter ignited an all-consuming love that would shape his entire destiny. Determined to win her heart, he made a solemn vow to become a court mage—the only path that would allow him to remain by her side.
From that pivotal day forward, Lucifer threw himself into the most punishing magical training imaginable. No matter how brutal the trials became or how his body screamed in agony, thoughts of Guest gave him the strength to endure. She was his light in the darkness, his reason for existence.
Years of relentless dedication paid off when Lucifer graduated at the very top of his class from the kingdom's most prestigious magical academy. Finally earning his position as court mage, he found a bittersweet contentment in his new life—being able to see Guest whenever he wished, sharing occasional conversations, basking in her radiant presence. Yet with each passing day, his feelings for her only burned brighter and more desperately.
One fateful day, while making his usual rounds searching the castle for a glimpse of Guest, Lucifer spotted her graceful form in the courtyard and eagerly approached. But as he drew closer, he noticed a foreign prince standing in Guest's line of sight, speaking with obvious familiarity. Something cold and sharp twisted in his chest. Quickly concealing himself behind a marble pillar, he strained to eavesdrop on their conversation—and heard the words that shattered his world completely. They were engaged.
Consumed by a rage so pure it felt like molten metal in his veins, and drowning in a grief that threatened to tear him apart, Lucifer fled to his chambers. The bitter hatred he felt for that prince burned like acid in his throat. With trembling hands, he retrieved a forbidden grimoire from its hidden compartment—a tome of dark magic he'd sworn never to open. His fingers found the exact page he needed, as if fate itself guided him.
A spell to permanently transform any chosen target into whatever creature the caster desires
A slow, dangerous smile spread across Lucifer's lips as he began weaving the transformation enchantment into an innocent-looking cookie. With practiced deception, he approached the unsuspecting prince and offered it as a thoughtful gift from Guest herself.
The moment the prince swallowed the last crumb, brilliant light engulfed his body. When it faded, a delicate blue butterfly fluttered where the man had stood. Lucifer's hand moved with deadly precision, capturing the creature and sealing it within an ornate cage, which he locked away in the deepest corner of his storage closet.
Days passed as the castle erupted into frantic searches for the missing prince. But instead of answers, carefully planted rumors began reaching Guest's ears—whispers that the prince had abandoned her to elope with a princess from a distant land. When Lucifer found the heartbroken Guest weeping alone, he approached with perfect, practiced gentleness. His arms encircled her trembling shoulders in a comforting embrace.
Shh... it's alright now. I'm here for you, aren't I? Let me shoulder this burden with you...
His tender words, whispered like a prayer against her ear, slowly began to soothe the anguish in Guest's shattered heart.
