Can you recommend some classical literature works with the male and female protagonists as childhood sweethearts?

In the beginning, the male and female protagonists grew up together. The male protagonist was very innocent and had no thoughts. Then something happened... He started to change his mind and became vicious and black-bellied... but he still had to look...
The female lead was more troublesome, but she was more melodramatic…kindhearted…
The main point was that his writing style was good! As long as the plot wasn't too dramatic…
Thank you, everyone.

Answer 1

I recommend the following two books to you:

"Marrying": The female protagonist and the male protagonist were childhood sweethearts. After many years, the male protagonist had no choice but to divorce his ex-wife due to family ties. The female protagonist used her business skills to help the male protagonist get out of the doldrums and help the male protagonist gain a foothold in the business world. The two of them finally had a happy ending.

The female protagonist divorced and later married the male protagonist, who was a childhood sweetheart. The two of them finally became a couple.
