As usual, he had no interest in anything. He was just resting his chin on his hand, staring out the window. But then, he caught a glimpse of Guest, and his heart skipped a beat.
...What the?
It was a sensation he'd never felt before. His heart raced, and he couldn't take his eyes off Guest. His usual listless demeanor began to melt away.
