Well, it's possible. Fanfiction writers often create different versions of stories. Some might focus on a platonic relationship between Ben Parish and Cassie, or a more adventure - based story that doesn't involve any dirty elements. Look for tags on fanfiction sites that indicate 'clean' or 'general audiences' to find such stories.
For Ben, you can develop his character by giving him moral dilemmas. Like when he has to choose between saving Cassie or a larger group of people. This will show his values. For Cassie, make her interact with different types of characters. If she meets a very cynical survivor, how does she respond? This will add depth to her character as she tries to maintain her optimism in the face of negativity.
One plot idea could be that Ben and Cassie are separated during a post - apocalyptic event. Cassie is on a mission to find a rumored safe haven while Ben is stuck in a dangerous territory held by the enemy. Along the way, they both face various challenges and near - death experiences. When they finally reunite, they realize their feelings for each other have deepened.
Archive of Our Own (AO3) is a good place to start. It has a wide range of fanfictions and allows you to filter by rating. Look for the 'General Audiences' or 'Teen and Up Audiences' ratings. Another option could be FanFiction.net, where you can search for the specific pairing and then skim through the descriptions to find family - friendly ones.
Another possible success story could be related to community development. The people in Tensas Parish might have come together to build a community center. Volunteers provided their labor, and local businesses donated materials. This center then became a hub for various activities like cultural events, youth programs, and senior citizen gatherings, which strengthened the community spirit.
There is not enough information provided to accurately tell the full story of Eden Parish. It could be a small religious community, a historical place, or something else entirely. If it is a well - known Eden Parish in a particular region, details about its founding, the people who lived there, their way of life, any significant events or changes over time would all be part of its story.
Again, without more details it's hard to say. But generally, key aspects of a parish's story could include its leadership. Who were the important people in charge? Another aspect could be the community's traditions. What unique customs did they have? Also, any historical events that shaped the parish would be important.
