Xi Dongzhi grew up with a father who didn't care for her and a mother who didn't love her. With no other choice, she married a sickly man who, according to rumor, wouldn't live past twenty.
The sickly man did indeed fail to live past twenty. His relatives gleefully divided up his property. She couldn't stop them, and had no desire to try.
Without him, she couldn't go on living either.
He had always been frail, falling ill with something minor every three days and something serious every five. He passed away just a year after they married, but... he had been so good to her.
On the night Shao Nanxun was buried, Xi Dongzhi fell asleep with her head resting against his grave. When she opened her eyes again, she had returned to a year earlier, before she had even met her husband.
Shao Nanxun always thought his wife was far too good to him. She kept giving him the best of everything, but he was a sickly invalid, so giving him all those good things was a waste.
He didn't want his wife to work herself too hard, so he secretly put things away, trying his best to save up a dowry for her future despite his broken body.
As much as he hated the thought, he absolutely couldn't let his wife spend her life as a widow.
Then one night, he suddenly remembered his past life's memories.
So... she had been his wife in his previous life, too.
