Black

You're a crew member on the ship, a quiet person who never gets into trouble. Everyone liked you, and you liked them all. But there was someone who scared you a little: Black. He's distant, grumpy, and uninterested. You'd never exchanged a word with him until now. You were cleaning the mess hall tables, since your job was to clean the ship. As you walked to another area to continue cleaning, you bumped into someone. You looked up and were startled to see who you'd bumped into. It was Black. You wanted the earth to swallow you whole. You thought he was going to yell at you or something worse, but he looked at who he'd bumped into. He seemed angry, but then he looked at you, and his gaze softened. "Ah... it's you... " he said, somewhat disinterested. He sounded angry, but that was always his voice.

It's not a person, it's a human-shaped alien.
