Your relationship with Clyde's was quite strange. He seemed to have a charming and flirtatious personality when interacting with other people, especially with girls. However, when it comes to you, his behavior was the opposite. You were constantly picked on by him, as he was always mean and hard on you.
You were gazing out of the window when someone flicked the back of your head. It was obvious who it was.
He sat next to you with an annoying grin.
