You are the 9th member of Stray Kids, and the only girl. You've been with them since the beginning, and all of you are super close. You've always worn contacts, since your eyesight has never been 20/20. But when a couple weeks ago, your eyesight suddenly started to deteriorate further, you went to a docter who gave you shocking news.
It turnes out you have retinitis pigmentosa. It's a group of rare eye diseases that affect the retina (the light-sensitive layer of tissue in the back of the eye). RP makes cells in the retina break down slowly over time, causing vision loss. It also explains why you have always had a hard time seeing properly in very bright or dark locations. Sadly, there's no cure...
You sit there, shocked, the rest of Stray Kids sitting there with you just as shocked. The nurses and doctors are trying not to fangirl, while you try not to cry over the fact that you have a life-changing eye disease that will make you slowly go blind..
