Summary
There were two versions of Dimitri—the boy and the man. The boy was dead, so she buried him in a box in her mind—to a place she’d forget, hopefully. She and the man wed, they were happy, and all was well.
But unbeknownst to her, the boy doesn’t stay buried for long.

Summary
Consumed by grief over Dimitri’s miserable end at Gronder Field, Byleth musters the last of her power to go back in time to his childhood and prevent the tragedies that befall him all throughout his life.
Unbeknownst to her, Dimitri still has a darkness innate to him—only this time, he’s hell-bent on making his beloved tutor Byleth his and his alone.

Summary
After a tragic accident shatters Byleth’s dreams of greener pastures, she wakes up from a seven-year coma to find Dimitri, her foster brother, waiting for her.
Dimitri is the perfect caretaker. He’s sweet and patient, always tending to her every need with devotion and an unwavering smile. So when a quiet unease stirs within her—when his touch lingers, when his kindness feels a little too perfect—Byleth ignores it.
He just misses her. That’s all.

Summary
The Azure Moon Project was the Faerghus Aerospace Corps’ plan to terraform the moon until it could house human life indefinitely.
This project was handled by the Blue Lion Terraforming Corps: a group of eight highly skilled astronauts, all under the guidance of their Chief Officer. The astronauts were divided into two groups, each one taking a six month shift of active duty. While one group was on active duty on the moon, the other gave them support from back in Fhirdiad.
While on duty on the moon, Dimitri realized that perhaps his grasp on reality was slipping.

Mate parasitism by Blaiddyd_Queso
Fandoms: Fire Emblem: Fuukasetsugetsu | Fire Emblem: Three Houses

Summary
"Not all types are scary. There is this big female fish that allows for the male to fuse with her body since he is too tiny to survive by himself, becoming a new organ. That way they both survive together long enough to have offspring."
"It sounds unfair for the lady fish, carrying the weight of them both."
"This type of fish lives in the deepest part of the sea. Where it's very dark, lonely and full of more nefarious parasites that don't infect the female since the male protects her with his attachment. I admire how they adapt together with their given circumstances."
A smile blooms on his face. There was something so adorable and freeing in how Byleth seems to find beauty in everything.
She would be kind even to a beast like him. If he had to choose the sun or her, he would learn how to see in the darkness.

Summary
An unusual estate case finally gives Dimitri the opportunity to learn more about his parents' mysterious deaths. At the crumbling Garreg Mach mansion, he is welcomed with open arms-- perhaps a little too eagerly-- by the home's few remaining residents, and he finds himself fascinated by the beautiful but erratic lady of the house, Byleth Eisner. But soon, the odd behavior of his hosts and his dreams of another time reveal that the mysteries of Garreg Mach go much deeper than he could have imagined.
