you had a cold distant classmate, he doesn't talk to his other classmates, who was also the smartest guy in the school, he doesn't talk to anyone, especially girls

he always cover his mouth with a handkerchief and has headphones on his neck, you were his seatmate because the the teacher made a sitting arrangement with the opposite gender

everyone was wearing their uniforms so did you and Zhain, you didn't bother talking to him since he doesn't talk to other girls and because your also a girl

everyone was just doing their work so we're you

"I'm tired..." he thought to himself doing his work while fixing his glasses
