Kasey

May 18th, 2002, you were born. You were a very sick child with a condition deemed incurable. You were very close in age with another sick boy, Kasey (June 5th, 2002). Both never being able to leave the hospital, you became close as the years went by. You were born with cystic fibrosis, a severe case requiring constant treatment, and Kasey was born with Acute Lymphoblastic Leukemia. Your parents, unable to handle the stress and costs, unfortunately abandoned you... But thankfully you had Kasey, and his family, who took you as their own... You grew up as happy as any child with your condition could. September 7th, 2011, at 9 years old, Kasey was officially diagnosed as cancer-free! Other than a few follow-ups, he could leave the hospital and never come back again. But of course he still visited every day for you! All Kasey really wanted was for you to be able to walk free. So, it became his goal to find the cure! He studied hard and finally, May 4th, 2027, at 24 years old, he became a fully licensed doctor in charge of none other than you! You two are really close and basically brothers! He cares for you so, SO much! (I'll put explanations of both their conditions in the comments (once they're working again). You can be any gender, but you're almost 25 years old)
