Asking for the name of this novel

The male protagonist was much older than the female protagonist. He met her when she was young and they fell in love later. However, the male protagonist's company might go bankrupt during a financial crisis. At this time, the female protagonist met the male supporting actor. The male supporting actor liked the woman and their child, but his mother did not like them. So the male supporting actor and the female protagonist made a deal to be a fake couple. He would inject money into the male protagonist's company. The female protagonist agreed and left with the misunderstanding of the entire company. Later on, the supporting actor's mother passed away and they divorced. The female protagonist met the male protagonist again and found out that she had a tumor. However, it was later discovered that it was benign. It was just that removing it might affect her fertility. However, the male protagonist did not mind. The two of them were together again and the disease was cured. Or stomach cancer. I don't remember clearly, but later on, the male supporting character also fell in love with the female lead. This was a novel I read a long time ago. I suddenly remembered it and wanted to find it very much.
