The Ballad of Frosted Hearts (!RotG!Jack Frost x Reader)

Awakened by the Man in the Moon, a new guardian emerges-the Cupid herself. Born amidst snow, roses, and angelic feathers, she embodies the essence of love, radiating purity & hope in a world teeming with magic and danger. As she takes her first steps into the realm of holidays, laughter, & tricks, Cupid discovers a dazzling & treacherous world, where light is never without its shadow.
Lurking in the depths of this supernatural realm, glowing golden eyes watch her every move, sensing her naivety & unpolished power. Shadows coil around her like inky tendrils, whispering promises she cannot resist. Her radiant soul becomes a beacon for an ancient evil, one that thrives in fear & despair. In her innocence, she unknowingly awakens the one being the Guardians swore to keep at bay: the Boogeyman himself.
Pitch Black has returned, and with him, chaos follows. Armed with new allies-terrors & legends as fearsome as himself-he has forged a dark syndicate, the Creatures of Chaos. Among them is the Cupid, lured into his web of lies & manipulation, her raw power feeding his insatiable hunger for dominance. Promised purpose, recognition, a place where she will never be forgotten, she becomes a pawn in Pitch's master plan.
As the Guardians are called to welcome their newest member, they remain unaware of the dark strings pulling her from the shadows. For Cupid's mission is clear: infiltrate their ranks, earn their trust, & destroy them from within.
Caught between light and shadow, love, & fear, she must decide who she is meant to be-and whose side she will choose-before her light is consumed by the darkness forever.
"Be rotten to the core," Pitch whispers, his voice dripping with venom. "And together, we will bring the Guardians to their knees."
