A Second Chance at Saving You(2023)

Watashi dake wo Aisuru Mujihi na Shougun

Empress Niobe Roden, the precious Blue Rose of the Rustan Empire, is in love with another man--the one to save her from her tyrant husband. She patiently waits for her lover Eloi, but all that returns is the news that the Emperor has beheaded him. Hopeless in her own imprisonment, Niobe ends her life only to be returned to the past–exactly two years before her marriage with Valon. With the second chance at life, Niobe is determined to conceal and protect her true love.
