Katsuki first noticed him during a rainy Thursday in autumn. Katsuki could not not notice him. He stuck out like a sore thumb in the crowd, with his yellow backpack, green raincoat and red shoes. It was the coat that bothered Katsuki the most. If you are going to pick yourself a goddamn green coat, at least match the green to your mob of green hair. (Or the one where Katsuki is triggered by a coat and Todoroki ends up being a matchmaker)
