Summary
What if Sitri never died, and Byleth was raised at Garreg Mach? What if Seteth was the one who Rhea decided to hire as a professor? And what if Byleth didn’t trust Seteth at all? (In other words: this is an AU where Byleth and Seteth switch places, yet still manage to fall in love.)
FINISHED!

Summary
“Seteth, come sit for a minute. Sit, sit.” The man topped off Seteth’s untouched cup in his hand, causing liquid to spill out.
“…Thank you,” Seteth said, unsure of what else to say.
“Now, you are family,” the man wheezed. The alcohol on his breath was far stronger than the beer from the keg. “All of my life…I’ve had a lump at the back of my neck, right here...”A just-for-fun FE3H x My Big Fat Greek Wedding crossover where Byleth introduces her fiancé to Jeralt's Mercenaries.

Summary
What if Byleth was a UFC fighter, and Seteth was her new trainer?

Better than it sounds (which is a compliment, I swear!). SUCH a quality read. Must-read for mecha and FE3H fans.

Summary
Her eyes are wide and eager. "Miss Varley…" he says reluctantly, silent for a beat as he finds the will to press on, "there is something we need to discuss."
The mood change is immediate and palpable. "Oh," Bernadetta says, sitting up a little straighter, face falling into worry. "Is there — I mean, have I done something wrong? I'm sorry, I know I talk too much, I just get so excited…".
Seteth has a difficult conversation with Bernadetta about feelings.
