the female lead had an affair with my fiance

Well, in the 'my fiance is in love with my sister novel' context, another option could be to talk to my sister. Maybe she is also confused or unaware of the depth of the situation. By communicating with her, I could find out if she has any feelings for my fiance and try to resolve the issue together.

😋I recommend the following novel to you: 1. "System Farming: Training the Dark Male Lead" 2. "Cannon Fodder Counterattack: Wife, Come Home" 3. [Dressed as a fairy brother's favorite pet] 4. [The handsome man of the mountains and rivers enters my tent] 5. "What a bloody fate." I hope you like this fairy's recommendation. Muah ~😗

She recommended "Flash Marriage: Mysterious Husband Doesn't Divorce." The male lead was a third-generation celebrity, and the female lead had an affair. The story was exciting and filled with the emotions of a wealthy family. I hope you like my recommendation. Muah ~

Well, it's a complex situation. You could also talk to your sister. She might not be aware of your fiance's feelings and might be able to help resolve the issue. If your fiance truly loves your sister, it might be better to end the engagement rather than living in a relationship full of tension and unfaithfulness.

Well, first of all, it's a tough situation. In a fanfic world, things can be really complex. If I were in this situation, I might try to have an honest conversation with both my fiance and my sister. I'd want to know exactly how they feel and why this has happened. Maybe there was some misunderstanding that led to these feelings.

Hey, I recommend the modern romance novel "Second Wife: President, Don't Come Over" to you. The story was about how the female protagonist accidentally found out that the man she had been married to for two months had cheated on her. Only then did she realize that he had married her with a goal in mind. The female protagonist resolutely decided to get a divorce, but she did not expect to find love in her future boss. The male protagonist helped the female protagonist many times, and the two gradually fell into a whirlpool of feelings. In the story, the male protagonist worked in the city government and met the conditions given in the question. I hope you like this fairy's recommendation. Muah ~😗

This Korean drama was called " My Love from the Stars."

It is not any book in the given paragraph, so the question cannot be answered.

This Korean drama was called Descendants of the Sun. The female lead was Liu Zhiya, the male lead was Kang Jihwan, and they both had a daughter. The daughter was actually the child of the female lead's husband's sister.

Well, it's a really tough situation. If your wife had an affair, you might want to seek professional help, like a marriage counselor. They can guide you through the process of understanding what went wrong in your relationship. You also should take some time for yourself to think about your own feelings. Do you still love her? Can you trust her again? These are important questions to answer before making any big decisions.
