Here’s a script template for a school entrance. The main character’s name is Jupiter, so you can change that to your main character by using CTRL+F, then typing in your main character’s name, then replacing all. You can change the actions of the extras to how you want them to react. They are currently set to be shocked/suprised.
You can give credit to @anniek.episode if you want.
