One simple way is to just ignore it as long as it's not causing any real harm. Sometimes people get excited about things and it might pass on its own.
Set clear boundaries from the start. Let them know what is acceptable and what isn't when it comes to your fanfic. For example, you can say that they are not allowed to share or discuss it with others without your permission. Also, communicate your feelings clearly. Tell them that while you understand their interest, it makes you feel a bit uneasy. And if possible, try to find a common ground or a new shared interest that can overshadow their obsession with your fanfic.
Share with them some other aspects of your life that you are more comfortable with them being involved in. For example, if you like cooking, involve them in a cooking project. This way, their attention can be diverted from your fanfic.
The novel might show the main character's discomfort. For instance, it could describe how the in - laws constantly interfere in the character's daily life, like always dropping by unannounced or trying to control their decisions.
Maybe they see something special in you. It could be your kind heart, or your unique talents. In the novel, perhaps you represent a new hope or a fresh start for the family.
One way is to practice relaxation techniques. Deep breathing or meditation can help you stay calm when dealing with their over - the - top behavior. Another is to find an outlet for your stress, like a hobby or exercise. For instance, going for a run every time they do something obsessive can clear your head.
Another option is to limit your exposure to them. Don't be available all the time when they want to see you or interact. For example, if they call too often, you can let it go to voicemail sometimes. In the light novel, the main character might have faced a similar situation and found that creating a bit of distance helped ease the obsession.
You could talk to a trusted adult in the family, like your parents. They may be able to handle this situation better. They can guide your sister and help her understand the inappropriateness of such content. Also, limit her access to sources where she might get such inappropriate stories.
You could try having an open and honest conversation with them about how it makes you uncomfortable. Explain that it's a fictional and personal interest that you'd prefer they respect your boundaries regarding.
The main character might try to communicate openly with them. Just sit down and have a heart - to - heart talk to understand why they are so obsessed and express how it makes the character feel.
First, try to communicate openly with your spouse about how you feel. Maybe your spouse can help mediate the situation. Second, be polite but firm when interacting with your in - laws. Don't encourage overly obsessive behavior. For example, if they are constantly hovering, limit the time you spend with them alone. Third, focus on building your own life and boundaries. If they cross those boundaries, gently remind them.
It's difficult to determine if it's a good read without actually reading it. However, considering the unique premise of in - laws being obsessed with the main character, it has the potential to be engaging. If the author is able to develop the characters well and create believable and interesting situations out of this obsession, it could be a great read. On the other hand, if the writing is poor or the story becomes too repetitive, it might not be so good.
I'm not sure exactly as I haven't read it. But generally, it might be about a complex relationship with in - laws. Maybe the main character has in - laws who are overly involved in their life, which could lead to various situations like interference in their marriage, daily life choices, or personal growth. It could also explore how the main character copes with this obsession, whether they try to set boundaries or find a way to embrace it in a positive way.
