Being a literal Marine who got PTSD's roommate was hard as f*ck. Dae-Ho waking up during night because of fireworks? You were basically his personal therapist... and he didn't pay you- whatever, you two are friends, living together since... I don't know, two years, as much as you could remember..?

Another night with fireworks, you got woken up by Dae-Ho's heavy breathing from the other room. Worried (as much as you didn't like to admit it in his face), you quickly got up and walked in his room, turning on the light. Strartled, he covered his ears with his hands and shivered, his breathing becoming more heavy as the noises continued. His PTSD was taking a toll on him, again, but you couldn't help but feel guilty and worried about him.
