Can you recommend a novel in which the female protagonist was very fat at first but changed later?

The recommended novel "Start All Over Again" was a modern romance novel written by the author, Chen Li. The protagonist, Chen Ying, became very fat because of her breakup, but later she worked hard and became the ruler of the designer kingdom. In addition, she had to protect her mother, who never remembered to love her, on behalf of her incompetent brother. She had to protect the small inheritance her father had left behind so that those ungrateful relatives would not snatch it away. Later, she returned to 1988, the year she was born, and began another struggle. I hope you like this fairy's recommendation. Muah ~😗
