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.
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.
It could be someone completely new, a character created just for this fanfic. Maybe he's a normal villager who has a kind heart and fell in love with Sakura when he saw her helping people in the village. He doesn't have any ninja powers but he has a great sense of humor and that's what attracted Sakura to him.
The character could also choose to distance herself from both the fiance and the sister for a while. This gives her time to think clearly without the immediate emotional turmoil of their presence.
One way to cope is to write down your feelings in a journal. It can be a great way to sort out your thoughts and emotions. Also, try to limit your contact with your fiance until you figure out what to do. Regarding your sister, be open and honest with her if you can, but don't blame her for your fiance's feelings.
This is a really complicated and heart - breaking situation. You may need to take some time to think about your relationship with your fiance. Consider whether this relationship is still worth continuing. If he can so easily fall in love with your sister, there might be some fundamental problems in your relationship with him. You could also seek advice from other family members or close friends who know your situation well. They may offer some practical solutions or at least some emotional support.
You could start by expressing your feelings to your fiance. Let him know how much his new - found love for your sister is hurting you. Maybe he'll realize the depth of his mistake.
I'm not sure about the exact plot as I haven't read it. But generally, it might involve a lot of drama and conflict. The main character suddenly finds herself married to her fiance's brother, which could lead to family turmoil, emotional confusion, and complex relationships.
