Sometimes you're already dating someone and you don't even realize it. Being "nice" equates to flirting, and soon, you'll be forced to give it a name. F!Byleth x Edelgard. Smut comes later, but mostly this is a story purely about flirting and being jealous. Out of 5 chapters.
After a long five years, Edelgard and Byleth finally meet again. They quickly realize the professor isn't on the side she though she was on. In other words, this is an alternate version of Silver Snow. Edeleth galore (f!Byleth). On-going, about nine chapters.
Byleth and Rhea are married, tied together forever. Yet Byleth has already lived one life and married someone else entirely; yet she promised HER they would be forever as well. Hmm. Lying about her past does her Byleth no favors, but embracing it is... hard. She has no idea how to be vulnerable but, that's what her and Rhea have in common right now. (Rhea/F!Byleth)
F! Byleth/ Edelgard von Hresvelg (one-shot). What is better than celebrating your favorite holiday with your wife and all of your best friends?
