Pushing up daisies (смешанная)

Aizawa had seen the worst of the world long before he was an adult, but by now he was sure that there was nothing that would surprise him anymore. He knew what he was getting into when he chose the path that he was following, and death and tragedy was bound to follow him. It was part of the job description after all.
But a cold silent night, of those he particularly enjoyed, he found himself feeling not so lonely during his patrol. He felt watched.
A mysterious kid seems to appear just at the right time and disappear just before he could really understand how, why and what he was doing there.
It was endearing just as much as he was mysterious, and Aizawa soon found himself feeling the need to protect uncover the truth about the kid.
What hadn't occurred to him is that maybe there was a reason as to why he couldn't touch him, as to why he could only see him at night.
What if-
What if Midoriya Izuku was no longer a kid?
