"Fah Sai" is a rising star in the violin world, radiating brilliance and elegance every time she takes the stage. But behind the dazzling spotlights, her life is a prison of paranoia. Threatened and hunted by a mysterious stalker, she lives like a small bird trapped in a gilded cage.
Her lost freedom leads her to "On," a top-tier bodyguard with a wall of ice around her heart. Cold, disciplined, and unyielding, On steps into Fah Sai’s life to control her every move in the name of security.
From stifling friction and fierce resistance, a profound sense of safety slowly begins to bloom as danger creeps ever closer. Amidst the echoes of gunfire, the stains of blood, and the haunting ghosts of a traumatic past, the melody of Fah Sai’s violin begins to melt the frozen heart of her protector.
However, their growing love must face the ultimate test when a mastermind in the shadows prepares to do whatever it takes to claim this "little bird" for their own.
"My duty is to keep you breathing... Your satisfaction is not in the contract." That was what the cold bodyguard once told her... before she proved she was willing to trade her own life to protect the smile of the woman she loved.
