Take My Life (Sick AU)

When Izuku was four he thought he never received his quirk. Despite trying many things, it became clear he could not do anything. Even going to the doctor, it was unclear and he was assumed quirkless.
On top of being quirkless his health kept declining more and more each year. At the age six, he is finally diagnosed with a fatal quirk disease that will take his life in 8 years.
Which is shocking, because Izuku doesn't have a quirk. Right?

Bakugou, his closest friend, watches over him and helps him to and from his many hospital visits.

However, something unexpected happens during his hospital visits that changes Izuku's life forever.
And in turn, Izuku changes someone else's life forever.
