On the Day of the Substitute Marriage, I Wore Mourning Clothes to Marry the Heir Apparent

The day my sister ran away from the wedding, the whole family knelt down and begged me to marry her. I smiled and got on the sedan chair, wearing mourning clothes and a filial piety hairpin. People all over the capital are calling me crazy, but they don't know—— This is the day I've been waiting for. On the wedding night, the prince pinched my neck: "Aren't you afraid of death?" I put the dagger against his heart with my backhand: "What a coincidence, I died once." He suddenly smiled and whispered something. That night, my fiancé, whom I killed with my own hands, survived.
