Use the System to Travel Through Time to Marry Your Step-Sister's Critically Ill Fiancé

Use the system to travel through time and become a poor little boy who has been living in his grandfather's house in the countryside since he was a child and was not well received. I thought this would be miserable enough, but in the end, I had to celebrate my step-sister's marriage to the eldest son of the general's palace who would not live for a few days. Since the Shangshu Mansion can't accommodate me, my scumbag stepmother will return the dowry left by my late mother to me. I will take the dowry with me to get married. At worst, I will be a rich widow waiting for my sick husband. As a result, my sickly husband was cured by me, and he became a high-spirited major general, and fell deeply in love with me. I can't bear such strong love! I just wanted to live my own peaceful little life, so I ran away and he chased me...
