Finally
https://www.fanfiction.net/s/2170362/1/Finally
Lemon; Set three years after Meteor, Cloud and Tifa raise chocobos together while still trying to resolve their feelings for one another.

https://www.fanfiction.net/s/207989/1/Forever-and-Beyond
A series of moments between Cloud and Tifa as they struggle to live out what time is left after she is diagnosed with a rare fatal disease similar to brain cancer. The conclusion to a four-part series (The prior parts didn’t meet the cutoff I set hence their lack of mention).
