We all know about Yu Zhengchuan's background.
His father passed away early.
Later, his mother remarried, and Yu Zhengchuan, along with his five-years-younger sister Yu Duo and his grandmother who had an eye disease, depended on each other for survival.
The year Yu Zhengchuan went to university, his grandmother passed away.
In this world, Yu Zhengchuan had only one relative left, his sister Yu Duo.
Yu Duo didn't get into university that year.
Later, she entered a technical college to study accounting.
And after graduating, she couldn't find any decent job. When she was 24, she married an ordinary carpenter from Jinde County.
This brother-in-law was named Miao Guiming.
At first, he seemed to have a decent character.
He was hardworking and willing to work, and his family background was also typical, so Yu Zhengchuan didn't oppose this marriage.
Unexpectedly, three years after marriage, Miao Guiming's character changed drastically.
