Answer: This is not an easy answer, since it depends on the person writing it. Let me see if I can spark some ideas that will help you write a good introduction.
The Perks of Being a Wallflower champion and celebrates inclusivity and tolerance by showing both how people can blossom when they are accepted for who they are and how painful life can be for people who are ignored or mistreated. In your introduction, you need to show some personal connection to that story, situation, feeling, perspective, etc. To do that, think about your past, people you know, situations you have dealt with, or how this type of experience might have touched you in some way.
For example, if you had a similar experience, you might write "When I was growing up, I was always teased about being a nerd because I enjoyed techy things and hanging out playing video games. I felt like people didn't always acknowledge me or take an interest in what I liked, so I literally felt like a wallflower. In my own personal struggles to be recognized as an individual, I connect with the inclusivity and tolerance theme in the book "The Perks of Being a Wallflower" which resonates with my own past experiences and feelings of exclusion. In the book, Charlie is trying to come to terms with major traumatic events from his past, but he doesn't even realize that he has repressed memories of still more trauma."
Hopefully, this explanation helps you find your own voice!
