Determined to save Alexis—her favorite character from a past life—from descending into darkness, Isabella enters into a contract marriage with the young, grieving orphan. Having suffered severe mistreatment as an illegitimate child, Alexis receives a boundless outpouring of love and devotion from Isabella throughout their three years together. However, as stipulated by their initial agreement, Isabella steps away and leaves him behind the moment he comes of age, carrying a heavy secret of her own. Eight years later, fate unexpectedly reunites the former spouses: a wife who vanished into the shadows, and a husband whose memories of his beloved wife were tragically lost. Now a powerful emperor feared for his cold and merciless demeanor, Alexis crosses paths with Isabella once more. This sets the stage for a poignant, bittersweet adult romance defined by mutual longing and repeatedly missed connections as the two grapple with their entangled past.
