The short story below is correlated with the image above.:

"My name is Catherine. I was born with a weak immune system. So weak that if I end up catching something, I could die. It's a curse I'm permanently bound to. Before I could go to school, I had to go to the doctor with my parents to prepare for interacting with other kids. I was recommended to wear a mask the whole day and could not take it off. Every school year, the other kids looked at me funny. Some spread rumors about me. Some even tried to take my mask off. The moment they tried, they ended up on the ground, covering their own face. I got mixed reactions from my teachers when this happened. Some didn't care and some reprimanded me. One time when a teacher punished me for not taking my mask off when answering her question, I told my parents and I cannot tell you how small that teacher looked when my parents yelled at them for putting my life at risk. I barely had friends. Not many people were understanding of my predicament and would sometimes ridicule me for wearing my mask.
Finding a job was tough. I wanted to pursue a career in fashion design, but my interviews did not go well. They either thought my mask was unnecessary, unappealing, or had trouble understanding me, even though I did my best to make my voice clear enough. I ended up getting an office job that thankfully didn't require me to speak too much. However, that didn't go well after being poked and prodded about my mask by my coworkers. While some were understanding, others thought I was full of **** and ridiculed me for it. I ended up quitting when the ridicule took a toll on my mental health and made me feel ashamed to wear this mask, even though I needed it to live.
As the years go by, it got worse for me. I was harassed everywhere I went with my mask by men, women, even teens. I could count on two hands the attempts to rip my mask off by random strangers. Sometimes they got knocked out by either me or someone else, sometimes the police were called. Fortunately, I was never arrested, but I was ready to lose my mind. My parents recommended I ignore the assholes, and I lost it on them, blaming them for my condition. I may have stepped too far with that, but ignoring doesn't always fix the problem.
My patience was disappearing, and my tolerance for other people was gone. I hated humanity. Humanity to me was an unavoidable disease that was putting me at risk. I had nothing but a desire to be free from that encroaching disease, finally take this wretched mask off, and smile for the first time in decades. But then, nobody will ever see my smile, except for me. It'll be like how it has always been. A cruel fate was handed to me, and my only escape is death. Ironic how much I want to escape, yet I want to live. What cold mortality."

I don't have any plans with this character, but I feel like sharing.
