Can you recommend a gangster romance novel?

I miraculously found a romance book that I missed a lot when I asked about it earlier, and my confidence in knowing it increased greatly. So he asked again. The female protagonist drank an aphrodisiac in her family's restaurant and was rescued by a gangster and brought back to the gang. The two of them went to bed. After secretly living together, the female protagonist began to slowly accept it. However, the female protagonist's family was a famous big company. They would not agree to have anything to do with the underworld, so they kept it a secret until the female protagonist became pregnant and went to the hospital for an abortion. The reporters took pictures of her. Although the male protagonist covered her face with clothes, the family still found out the truth from the watch she was wearing. After the two of them went to the female protagonist's house to beg for forgiveness, the male protagonist did not hesitate to cut off his own hand. Later, he was chased out of the house and cut off all ties with her. Many years later, the female protagonist's father finally expressed his blessings to these two people who were desperate for love through television. [Details: The female lead was born into a wealthy family and had a tracker implanted in her arm to prevent kidnapping. It was later removed by the male lead.]
