"..Mm.." He hummed.

That's the first noise you heard that ever came out of him!

One day your class was being so loud, gossiping, talking about the latest phones and such. While you were sitting at your desk, actually trying not to fail, you heard something that didn't sound a thing like your loud classmates. It sounded like Kay. He was humming a song in his head until he hummed out loud for a split second.

Kay sat in front of you. He never left his seat until it was time to leave.
