It was a one shot. It took place inside of a hospital, one of the elderly patients had a highschool age son, his eyes were drawn very beautifully almost as if the galaxy was stored inside of them. A lot of supernatural occurrences start appearing inside of the hospital, blablabla mc ends up being kissed by that boy who promises he will cure his illness since he is a nice person. After that the boy and his mother are never seen again. Oh and the boy can't speak properly
