One common problem is the ethical aspect. Kidnapping is a serious crime and presenting it in a way that might be romanticized in fanfiction is not okay. It can give wrong ideas about relationships and boundaries.
Rather than seeking out this specific and potentially concerning type of fanfiction, you could explore fanfiction in genres that are more widely loved and appropriate. For example, there are great fanfictions about characters growing and learning in a fictional world, or ones that explore the backstories of beloved characters in a positive light.
One major problem is the ethical aspect. Kidnapping is a serious and traumatic crime in real life, and portraying it in the context of a pregnant person in fanfiction can be highly disturbing. It may also trigger negative emotions in some readers who have experienced or are sensitive to such situations.
The main ethical concern is the potential harm it can cause to readers, especially those who have had experiences related to abuse or trauma. This type of fanfiction can be triggering. Also, it goes against the values of respect for human rights and dignity as it often involves non - consensual and immoral situations.
These types of fanfiction often cross the line into non - consensual and potentially abusive storylines. They may romanticize or downplay serious issues like coercion and the violation of a person's freedom. This can be harmful to readers, especially those who are vulnerable or impressionable.
Perhaps the obsessed guy has a change of heart. He realizes his actions are wrong and lets the girl go. But this ending often comes with a complex set of emotions and consequences for both characters as they try to make sense of what has happened.
There are ethical concerns with such a topic. It's not something that should be encouraged. Instead, you could look for fanfiction about pregnancy in a more positive and safe context, like a story of a pregnant character supported by family and friends during the pregnancy.
One common theme could be the rescue of the pregnant woman. Maybe a heroic character steps in to save her from the kidnappers. Another theme might be the psychological impact on the woman during her captivity. She could be dealing with fear for herself and her unborn child.
Often, the theme of rescue is present. It could be the girl trying to rescue herself or her friends and family attempting to rescue her. Also, there can be a theme of psychological manipulation as the obsessed guy may use various tactics to control the girl.
Rather than seeking out such specific and potentially concerning fanfiction, you could look into fanfiction that focuses on positive relationships, growth, and family in a more healthy and consensual way. For example, there are many fanfictions about characters building families through love and mutual respect.
