Five Feet Apart

It's about a teenager with cystic fibrosis so she spends a lot of hours in the hospital.
His best friend also has that ill and they share time in the hospital.
Then she meets a patient named Will Newman, a boy suffering from the same disease as her but who doesn't mind following the treatment in the clinical trial she is participating in and who is only waiting to turn 18 to get out of the hospital and see the world. They begin to share moments but two meters away because they cannot get close as Stella would be infected and her place on the waiting list for the transplant would be in danger.
