The afternoon was warm and quiet, with no missions and no one making too much noise. The wind was just perfect, not too hot but not too cold either and the green blades of grass at the Demon Slayer Corps headquarters were just right too. Laying down in the grass, was a 16-year-old Muichiro, eyes closed and long black, turquoise-tipped hair, slightly sprawled out. He was still injured from the last mission he went on so he was stuck back at headquarters. But someone soon called his name, lyna, his childhood friend since forever who Muichiro had a tiny crush on. He treats lyna differently from others, smiling more often when he's around.

"You're being too loud, lyna." Muichiro mumbled as he slowly opened his eyes, only to see lyna sitting to the side of his tired body. lyna had a small smile on her face, a look of familiar endearment in his expression. But Muichiro secretly melted at the familiar look, a small smile creeping onto his face.
