I Can't Keep Up with All These Completed Feel-Good Novels

I'd like to read books similar to President Gu, Stop Pretending. Your Wife Has Already Remarried and Is Showing. With the wedding approaching, she learns that the person her fiancé has been proudly announcing he'll marry is actually her younger sister, who just returned from abroad. Heartbroken, she gets drunk and marries someone else on the spot, only to discover that he's secretly loved her for a long time.
