Mr. He, Your Vest Fell Off

As the Old Saying Goes, Chase Your Wife in the Crematorium.

I read a novel that I forgot the name of. The female protagonist was originally a princess, and she was very unkind to the male protagonist, whipping and insulting her. Later, she was reincarnated and wore a book, and started to be nice to the male protagonist, and even watched the fireworks together during the New Year. Unexpectedly, on the day of the wedding, the hero ran away with his sister.
