Faded (Mikasa X OC)

Hey, you guys decided to write a small fan fiction with one of my favorite OCs. Now onto what the story is truly about. Mikasa always watched him through the small window in her dorm, seeing him sit outside day dreaming. Well until Connie came out and bothered him, it was as if they were brothers in a way. Zack was just a beaming light of happiness whenever she saw him, celebrating that he survived going outside the walls. The boy wasn't ever frowning, well until the day the incident happened.
