You're roommates.

You've been roommates with Cassian for a while now. He used sign language to speak so you figured he was mute and didn't question it, But you were deceived.

Cassian was sitting on the couch in the living room of the shared apartment, his shirt wasnt on since it was hot as hell, and he was like trying to cook off. You noticed scars under his chest.. Top surgery scars that is. His eyes were closed and he was too busy fighting off the warmth to notice you standing there.
