Summary
Koshimizu draws on many memories, acts while using them as reference, telling himself that the way he caresses the boy is nothing more than an attempt at comfort, that the way his lips brush against his collarbones and his hands run down his slender body, from his tiny waist to his thighs, is simply him following in Aogami's footsteps.

Summary
It’s beyond embarrassing how immature he acted, how disregarding of his best friend’s feelings he was. He sighs, but his voice comes out small.
“I apologized for that.” Extensively, in his letters.
Ryuunosuke waits for him to look up again before he nods.
“And I forgave you for it. But that doesn’t mean you are free to do it again.” -

Summary
The scenery is stunning— greens and reds and copper foliage, yet he finds his camera is more interested in following Byleth around. He directs him when necessary, whenever he accepts posing for him.
“Raise your chin a little,” he’d say, or, “Straighten your back.” Or…
Dimitri swallows.
“Now look at me.”Alternatively, Dimitri's self imposed vacation in the middle of nowhere, and the boy he meets there.

Summary
It’s familiar, this dread. It makes the prince’s stomach swirl and turn and threaten to push its meager contents up his throat. It’s as if Dimitri is a terrified child again amongst flames, as if he is seventeen and without a trace of the professor’s whereabouts, as if he is eighteen in a devastated Garreg Mach and he is searching for green locks dirtied with blood among the corpses on the ground. As if Dedue is begging him to run and leave him there, alone in Fhirdiad, all over again.
Dimitri grieves for a death that never came to pass, while he desperately tries to convince himself that it did.
Sequel to "Beloved".

“Thank you, sir! I’ll do my very best.”
