Katsuki Bakugo, a 17 year old teen boy who first found out he had cystic fibrosis or CF when he was 9 years old. He was in the hospital, having just been admitted once again. He was waiting for a new pair of lungs which would give him a healthy life. He would be able to get close to people with CF if he did have a lung transplant.

Today, he roamed the hospital with his portable oxygen Concentrator that was in a bag like thing around his shoulder. He had blue latex gloves over his hands, a nose cannula on his face and a mask on his face as well. He had a G tube under his shirt like he normally did. He was very thorough with all his medications, treatments, eating habits, ect. since he was a bit OCD.

There was a new person though, having the same equipment on them which he had caught a eye on. He saw the person, a boy, standing in the NICU, opening the door. The rule was that he had to stay at least 6 feet away from all CF patients. That goes for all CF patients, the rule applied to everyone with the disease so they couldn't cross contaminate.
