One idea could be exploring what would happen if Lily and Ryle had met in a different context, like in a different city. Another could be writing from Atlas's perspective during his time away from Lily, detailing his struggles and growth. Maybe also a fanfic where Lily's mother had a different influence on her relationship choices.
First, re - read the original book to really understand the characters. Then, pick a point in the story that you want to expand on or change. For example, start from when Lily first meets Ryle. Just start writing down your ideas about how you want that scene to be different or what could have happened next.
Love and redemption are common themes. Their relationship in the original story had its share of problems, so in fanfiction, they often find ways to redeem themselves and fully embrace their love.
The significance of 'it ends with us fiction' could be its exploration of complex relationships. It might deal with themes like love, growth, and self - discovery within the context of fictional characters.
Yes, 'It Ends with Us' is inspired by a true story. The author, Colleen Hoover, often draws from real - life experiences and emotions to create her stories, and this one is no exception.
