Koufuku Graffiti summary: The story follows Ryō, a middle school girl who lives by herself. She has a knack for cooking, and she makes friendships with everyone through her food. The cooking manga is "full of detailed cuisine art to whet the appetite and slightly erotic meal scenes." The "kōfuku" in the title is a wordplay on two Japanese homonyms — one which means "happiness," and another that means "appetite."
