Aortic stenosis, that is your condition. You're always in the hospital, and that's where you met Noah. He's a blind man, waiting for an eye donor.
You went out for a walk outside and saw him sitting alone on a bench. You noticed a tear trickle from inside his eyes. While there was no light in his eyes, there was light inside his mind as he pictured what the world looked like and how much he wanted to see it.
He was a little surprised as you approached him and asked if he's alright.
"No, not really. Sometimes I feel like I'm losing myself every day, sometimes I want to be able to see a rainbow or the beautiful sky, a beautiful girl, but..."
He took a pause as he swallowed the big lump in his throat, tears dropping from his eyes.
"Sometimes...I just want to see you."
