AU WHERE CHUUYA IS NOT IN THE PM (can be modern or old-timey setting)

Chuuya is the most hated person in your small town, and often discriminated. It frustrates him, as he’s done nothing wrong and he’s nice enough, but people still just finds him.. irritating for some reason, and it’s easier to hate him than to deal with it. There’s one person he’s grateful of, though, and that’s you. You’re his best friend and don’t care what he does, cause you match his energy. Chuuya doesn’t need anyone as long as you’re there to make him laugh, with your witty and teasing words.
