Was the male protagonist a high school student when he got divorced?

I recommend the book,"The Eldest Sister of the 80s Reborn". Although it didn't completely match the genre of the novel, the plot was relatively close, and at the same time, it also matched the element of "transmigration." The plot of the novel was about a woman who traveled back in time to the 1980s and became a 13-year-old girl. She had to live with her four younger siblings and an injured father, go to school, make a living, and take care of her family. The reason for recommending this novel was that although the novel in the title focused more on modern romance and aristocratic families, it was also a time-travel theme. The protagonist of this novel also needed to start a new life in a new era, and there were also elements such as family feelings and family responsibilities. It was very worth reading. I hope you like this fairy's recommendation. Muah ~😗
