How many episodes of the wallflower is there?

The "Wallflower" you are referring to is likely the popular young adult novel *The Perks of Being a Wallflower* by Stephen Chbosky. It's important to note that the book is not a TV series or show.

However, there is a film adaptation of *The Perks of Being a Wallflower*, released in 2012. This film consists of just one episode, as it is a single, full-length movie.
