Sir-uwu
Izuku passes away at a young age. Katsuki, who had yet to fall into his ego and bastard-like attitude, never allowed the people to blur his sight or cloud his feelings. Thus allowing him to becoming a good willed boy who wishes to become just like All Might.
"I'm doing this for you Izuku..." he told himself quietly one night, to his surprise, he received a haunting yet hopefully reply.
It was Izuku, but he had died a year ago? That happened? Looking at himself in a mirror, he couldn't believe his eyes.
"Izuku?"
"Kaachan!" Izuku asked surprised as his childhood friend finally noticed him after all these years.
