Another idea for a 'kyou x tomoya fanfic' could be a story set in the future. They have grown up and are trying to pursue their dreams. However, they still find time for each other and support one another through the difficulties of adult life.

A simple adventure - based fanfic could be where Tomoya and Nagisa decide to go on a road trip. Along the way, they discover new places, meet interesting people, and have heart - to - heart conversations that strengthen their relationship. They might even encounter some small challenges like getting lost or having car trouble, but they always get through it together.
Tomoya survives in Clannad After Story. The series takes the characters through various challenges and emotional arcs, but he makes it through to the end.
