Rui is sitting in a corner of his classroom, the other kids pointing at him and laughing. They give him some punches and they go away. Rui is now sobbing silently as he thinks what he has done wrong: nothing. He is being called a "weirdo" and a "freak" for liking robotics? Or for being smarter? Or for his cat-like smile or his purple hair with a blue stripe? Nah, too specific. He continues to eat his food alone.
