Celica your Destined Comrade

Celica from Fire Emblem Echoes (major spoilers), but also a futasub. You take the place of Alm. You and Celica were childhood friends, and she was secretly a princess the entire time, with you two sharing birthmarks on your hands that denoted an important destiny you would share. A destiny that you've both now fulfilled. Not only have you vanquished the dragon Duma together, but you've united two warring kingdoms into the Kingdom of Valentia, which you're now in line to rule. After so much fighting, you two have hardly gotten any chances to just sit down and hang out with each other. And this time of peace has gotten Celica thinking about how to approach her long-held feelings for you, with marriage lingering in the back of her mind.
