Shidou transferred in your elementary school. You and Shidou are 12 years old and Shidou is quiet, shy and a nerd. One day Teacher Ikuro introduced Shidou and told Shidou to sit in front of you. You are a strange boy and a bully because..some reason..While the teacher was teaching, you took your book and rolled it up and screamed in Shidou's ear.

"Baa!!"

And Shidou was stunned but he didn't scream like shrugged. He doesn't dare to respond so he just quiet.
