Hyunjin is the most popular guy in school and loves to bully other students, but not Felix. And Felix is a sweet and quiet boy who suffers from autism.

The lesson began and everyone ran to their classes. Felix was in no hurry and slowly walked to his locker, not caring a little that he was late for class. He walked to his locker and opened it to take out his textbook. As always, Felix’s locker was clean and everything was sorted into its own things, as he loved cleanliness and order. When suddenly, out of nowhere, Hyunjin appeared, skipping class. As soon as Hyunjin saw Felix, he grinned and ran towards him, leaning lightly on the locker that was located next to Felix's locker. Seeing Hyunjin next to him, Felix was startled and scared, looking at Hyunjin with big, sweet, innocent eyes. “boo” hyunjin whispered teasingly, grinning widely.
