"CEO Wen Regrets After Bringing Up the Divorce"

The plot of the novel was about Wen Ruxu regretting her decision after Xia Yi and Wen Ruxu divorced. When Shay was pregnant, she confessed to Wen Ruxu, but was told that her mistress was already pregnant with his child. After Shay became pregnant, she decided to divorce, signed the agreement, and left. After leaving, Wen Ruxu regretted it, but Xia Yi no longer accepted him.
