Please recommend a sad, fast-acting novel. Thank you.

Find a novel and wear it quickly.
I can also recommend some things that you can wear quickly, and then the more sad ones. Thank you. The female lead was (probably) a campus goddess in the third world (the male lead liked her). Later, they got together, and the male lead's mother found out.(To be precise, the fiancée that his mother prepared for him found out and told the male protagonist's mother). Then, his mother gave the female protagonist a lot of money to let her leave the male protagonist. The female protagonist seemed to have a mental illness and agreed. Then, on the birthday of the male protagonist or the female protagonist, the female protagonist went home (they lived together) and told the male protagonist that she had something to do. She put the check on the shoe rack. The male protagonist's mother came to the male protagonist's house and told him that the female protagonist had accepted her money. It was... Then, the male protagonist saw the check on the shoe rack and drove out (but the female protagonist had already gone abroad). He got into a car accident halfway and lost his memory. The female protagonist was studying at a famous brain doctor.
A few years later, the male protagonist's grandfather had a cerebral hemorrhage (probably), and the female protagonist came back for treatment (not to mention the reason). Then, the male protagonist's mother said that the female protagonist left the male protagonist for money, so the male protagonist began to mock the female protagonist as soon as he saw her. Then, the male protagonist was knocked unconscious by the female protagonist (probably), and later he recovered his memory. Later, the female protagonist became pregnant, but the fiancée was found by the male protagonist's mother.(It should be the adopted daughter now, because the male and female leads are married), she was pushed down the stairs (everyone thought it was the male lead's mother who pushed her), and then the female lead turned dark…
He couldn't remember what happened after that…

I recommend " Dress Up Quickly: Saving the Little Dainty Wife " and " Dress Up Quickly: The Supporting Female Character Doesn't Want to Be Dog-Leading."
If you like sad, fast-acting novels, I would recommend " The Female Supporting Character," and " The Female Supporting Character," as they have sad plots. In addition, these novels were all about time travel. I hope you like my recommendation.
