Help for the title of romance novel

The male protagonist's father was killed by the female protagonist's father. The male protagonist took revenge for his father and deliberately approached the female protagonist, forcing her father to go bankrupt and commit suicide. The male lead broke up with the female lead, and the female lead drove off the cliff in a moment of excitement, but she did not die and had plastic surgery.
A few years later, the heroine also deliberately went to the male protagonist for revenge, but the two ended up falling in love again.
[Note: The female lead has a younger sister. Neither of the sisters knows about finance, so their father wanted to recruit a live-in son-in-law to manage the company. He did not expect to invite a wolf into the house.]
It's not a hundred percent, it's a romance novel. The book mentioned that the male lead had a younger brother. The female lead's sister seemed to have become a couple with the male lead's younger brother. This book only mentioned a little. After the female lead fell off the cliff, the male lead also regretted it. When they broke up, he even gave her a set of jewelry, hoping that she could sell some money to live a good life after her family went bankrupt. That's all I remember. Please help me find it. Thank you!
It was really different from Lie Jin, but Lie Jin's writing style and plot were much better than that book.
