Honorary Golden Deer

Based off a male Byleth joining the Golden Deer, and the player - aka me - finding out that you needed to be female to romance Claude. Then to find out that Linhardt was the only viable romance for him and kinda became obsessed.
This is placed after Edelgard declares war and Lady Rhea and Byleth are missing. Five years have passed before the news of the professor's survival finds Linhardt's ears. Whispers of the Alliance leader, Claude, and his friends nearing the borders of their countries had Linhardt recalling the promise they had made five years ago. Now that he knew the professor was alive and it seemed Claude was ready to make his move, Linhardt needed to be ready for what was to come.
