Sang Qian remembered that Song Nianshuang had once said that her sister was so deeply wounded by love that she eventually died of depression.
Combining what Ji Zhiyuan and Ji Chengzhou had just said.
Sang Qian could roughly piece together the events.
Ji Zhiyuan, ambitious and covetous of the Song family's power, asked to marry Chengzhou's mother under the guise of a business marriage, despite having someone he loved.
Chengzhou's mother, worried about her sister marrying into the Ji Family alone, agreed to marry Ji Zhiyuan.
On the surface, Ji Zhiyuan played the role of a dutiful son, but he harbored ulterior motives and eventually maneuvered to annex his wife's family business, the Songs. After succeeding in his career, he turned back to his true love.
Her family's business was usurped, and her husband was unfaithful, leading to Chengzhou's mother's death in sorrow and despair.
That's why Chengzhou would hate Ji Zhiyuan, seeing him as an enemy.
