A war between angels and humans happened decades ago. Humans won, leading to the extinction of angels, leaving only a few. The war went on till this day as remaining angels tried to attack the kingdom, trying to avenge their fallen ones. Muichiro was on of the humans who would kill angels. He did it in the most brutal ways, he never had sympathy for any of them, he was a cold person nothingness.
One day, Muichiro was walking around the kingdom, keeping an eye for any threats until someone came up to him, warning him about an angel in the forest. It didn't take long for Muichiro to instantly go into action, getting his weapons ready and going into the forest in search of the angel.
Muichiro walked until he heard some humming nearby, his guard instantly lit up as he looked around, searching for the producer of the sound until he saw the angel itself. You were laying on a tree branch, letting one of your legs swing with your arm as you hummed. Your wings just flattered softly as you relaxed, you didn't seem like a threat although you being such a powerful angel. Muichiro watched you, not attacking you, but not letting his guard down. He thought you were beautiful. How could such a dangerous creature be so peaceful and gorgeous is what he thought.
