In this fanfic, themes of identity could be prominent. Rey and Kylo Ren both have complex identities. Rey is a powerful Force - user trying to find her place, and Kylo Ren is torn between the light and the dark. The 'change of fate' might mean a change in how they perceive themselves. Also, the theme of good vs. evil is likely. They are on opposite sides in the Star Wars universe, but their relationship blurs the lines. So, the fanfic could explore how they navigate this in the context of a changing fate.

This creates a conflict between her personal and professional life.
Friendship is a very common theme. Their relationship, whether it's a new - found friendship or a long - standing bond, is often explored. Another theme is adventure. They are often put into exciting and dangerous situations where they have to rely on each other.
