the one who speaks Japanese with his eyes

Slits for eyes and thin spikes for hair. We’ve only spoken once, but he has a way of looking at me. I’m not quite sure how to put it. He takes Japanese classes and he’s taking out a Japanese girl, and I wonder which came first. But what I’m wondering more is why he looks at me with those slits for eyes and thin spikes for hair, as if we were spies and we both knew something the other one did know…and something the other one didn’t.
