Synopsis

Born into a fallen noble family, Sakurako is arranged to marry the heir to the powerful snake god family. However, on the day of her wedding, Sakurako foresees that she will be brutally murdered by her husband, Touya... Protected by the bird god, Sakurako has awakened a precognitive ability limited to dangerous futures, just like a "coal mine canary." Determined to avoid death, Sakurako involves her family and tries every trick in the book to break the death flags, starting with breaking off her engagement, but Touya dotes on her, finding her "interesting woman"...? Breaking one flag only creates a new one elsewhere. (Source: Shueisha, translated)
