A fanfic like this could be really interesting. Maybe it delves into the backstories of both Fe Chrom and the villager maiden. It might show how their paths cross and how they interact with each other. It could also add new elements to the existing lore of the Fe universe, like perhaps a new magical ability that the maiden has that helps Chrom in battle.
There could be a lot of character development. For example, the maiden might start as a shy and simple villager but grow into a strong and important figure with the help of Chrom. And Chrom might also change, becoming more empathetic perhaps due to his interactions with the maiden. The fanfic may also include details about the world they live in, like the local customs of the village that the maiden comes from.
For Fe, you can develop the character by showing their backstory. Maybe they had a tough childhood which made them strong - willed. In the fanfic, have Fe make decisions that are based on their past experiences. For Chrom, emphasize his leadership skills. Let him take charge in difficult situations and show how his decisions affect the group. As for Olivia, show her kindness. Have her be the one who always tries to resolve conflicts within the group in a gentle way.
One possible plot idea could be a story of friendship. Fe and Chrom are friends, and they meet Olivia. Maybe they all go on an adventure together, exploring a magical forest. Along the way, they face challenges like difficult terrains and mythical creatures. They learn to rely on each other's strengths, with Fe's courage, Chrom's strategic thinking, and Olivia's charm and grace getting them through tough situations.
