Lightning in Spring

Minato is a college student with no future and no ambition. He spends his days goofing off, and his nights sleeping around. One day, he meets a famous prodigy artist named Riku, who attends the same college despite it not being an art school. Minato's first impression of Riku is that he's a weirdo, but when Minato has no place to stay one night, Riku lets him crash. After Minato sees him paint, urges start welling up inside him. Is he of all people falling in love...?
