Synopsis
Mercenary Kashumir, reborn in a novel, vows to protect her sister Aria from her dark fate.
Kashumir has spent her life working as a mercenary to provide medicine for her beloved younger half-sister, Aria. After a mission gone awry leaves her with a head injury, she awakens with memories of a past life—and realizes she's been reborn into the world of a novel she once read. In this story, her sweet sister Aria is meant to be the heroine of a romantic tale, while Kashumir herself was fated to play a darker role. Determined to rewrite this destiny and shield Aria from any harm, Kashumir sets out to change their story. But as she tries to guide events toward a happier path for her sister, she finds that her protective instincts and genuine care for those around her begin to attract unexpected attention. Now caught between her mission to safeguard Aria and the complications arising from her own growing relationships, Kashumir must navigate a world where the lines between ally and admirer blur, all while staying true to her vow to keep her precious sister safe.
