I, Cassia Louverno, daughter of a Simone Empire's Count, married Chester Greze, a commoner war hero, at the order of The Emperor. After living with him for 10 years with no love and money, I died of an incurable disease. I thought that I was dead, but no. At the same time of my death, I seem to have returned to the first day I met Chester, which is 10 years ago. However, I don't want to repeat the same life as before, so I am declaring a "strike." Cassia, who was blunt and knew nothing but war, was determined to live on her own without being discouraged. Strangely, Chester in this life continuously try getting into Cassia's heart. Cassia, who didn't hate Chester's efforts and changes at the same time, said, "I think that maybe I can manage your changes in this life."
