Class S (genre)

Class S is a type of genre in Japanese media that stands for "shōjo-ai" or "girl love." This type of media often depicts romantic and emotional relationships between female characters, but it usually does not contain any sexual content. You can think of it like a really close friendship between two girls where they have strong feelings for each other. It's kind of like how you might have a best friend who you really like spending time with and hugging, but you don't want to do anything more than that. Class S is just another way to tell stories about different kinds of relationships, and it's popular in anime, manga, and other forms of Japanese media.
