Yuri is a high school student who has been starved of love his entire life. His adoptive parents only care about their biological son, and Yuri is constantly bullied at school. Despite his loneliness and pain, he hides it behind a bright and gentle personality — a “smiling depression” type who always puts others before himself. His true identity is the descendant of the werewolf bloodline. Brian, the fallen heir of the vampire clan, has lived for centuries following his father’s strict belief: vampires must never drink human blood. That changes when his enemy shatters half of his heart with a single blow. Gravely injured, Brian falls into Yuri’s swimming pool in the human world — and is unexpectedly saved by Yuri’s blood. At first, Brian is only drawn to Yuri because of his extraordinary blood. He secretly follows and observes him, while growing increasingly jealous and possessive toward Lucius, the werewolf who has always stayed by Yuri’s side. But the closer Brian gets to Yuri, the more he is moved by this fragile yet kind-hearted boy. What begins as a hunger for his blood slowly turns into genuine love. Lucius, the young heir of the werewolf clan, was the only source of light in Yuri’s life before Brian appeared. Disguised as an ordinary high school student, Lucius has always protected and supported Yuri. As the star player and ace of the school football team, he is confident, charismatic, and admired by everyone. He takes every hit meant for Yuri and uses his warmth to thaw the coldness Yuri has carried inside. The relationship between the three is pushed to its breaking point through enemy attacks, betrayal, misunderstandings, and impossible choices. The antagonist Aiden is obsessed with the secret of the “pure blood” left behind by Brian’s father. He sets traps and hunts Brian relentlessly, eventually leaving Brian severely injured. To save him, Yuri cuts his own wrist and feeds him his blood, unknowingly forming a blood bond between them.

In a world where the sun has long vanished and eternal winter reigns, fire is condemned as the greatest forbidden power.The all-seeing Snow God rules the frozen world through colossal Snow Dragons, relentless guardians that patrol the skies, hunting down every trace of warmth and anyone guilty of the ancient sin known as fire. When young Lyra is struck by a deadly frost sickness, her father, Aldric, Lord of Winterfall, makes an impossible choice. Defying the Snow God's absolute law, he enters the forbidden ruins of an ancient civilization and awakens a forgotten flame. The fire saves Lyra's life—but at a devastating cost. As the Snow Dragons descend upon Winterfall, Aldric sacrifices himself so his daughter can escape. His final act awakens something far greater than anyone could have imagined. The Snow God has sensed the return of fire. An endless storm of Snow Dragons descends upon the city, reducing Winterfall to ice and ruin. Far away, a young noble named Kael, heir to the Darkhold, witnesses the destruction. Haunted since childhood by mysterious dreams of fire, he begins searching for the truth behind the world's greatest taboo. The deeper he investigates, the more he realizes that history itself may have been rewritten. Perhaps fire was never the true enemy. As Lyra grows older, she discovers that she is no ordinary survivor—she is the only person chosen by the fire itself. And now, the Snow God has turned its gaze toward her. Together, Lyra and Kael embark on a journey across the frozen world, pursued by the ruthless Ravok, the Snow God, and its relentless Snow Dragons. Their path leads them toward the legendary Hollow Sea, where long-buried secrets may finally be revealed. As the truth begins to emerge, Lyra realizes that what the Snow God fears most may not be fire itself—but humanity's ability to reclaim warmth, hope, and freedom. The battle between a god determined to preserve absolute order and the people destined to change the world has only just begun.
