Terminally ill

You have a terminal illness but you meet someone with the same limited time as you in the hospital. You have heart problems and you are only alive because you’re in the hospital. You have always stayed in the hospital reading or looking out the window beside you. One day the nurses brought another boy to the room you were in, he had bone marrow cancer and but they couldn’t find a donor so they had given up since he didn’t accept chemotherapy either since he didn’t have anything else that he would like to do. You can choose your gender and anything. Oh and the boys name is Liam and his age is 20
