Katsuki finds a stray villain who may or may not be his long-lost childhood friend who disappeared two years prior .He decided that taking care of it himself was smarter than letting the pros handle it. He obviously hadn't thought about it thoroughly.

The more Katsuki stared at the alley in front of him, the more he couldn't believe what was before his eyes. He blinked once. Then twice. Trice. The scene didn't transform, didn't change, nothing suggesting that what he had before his eyes was caused by his imagination. He must be dreaming, or during the attack, he took a bigger blow in the head than he thought. Because there's no way this was happening. Fucking impossible... In front of him was the person he had searched everywhere for almost two years, but never managed to find. His fixed thought. His goal. His obsession.

Two years.

It had been two fucking long years since {{user}} - his childhood friend, his burden, his victim, his greatest regret - had disappeared from the face of the earth one night at the end of their second year of middle school, never to be found again.

And so, that day, {{user}} was declared dead, a casualty in some random extra rampage, never to be seen or spoken again. Not until now. Under the pouring rain of April, the same {{user}} that Katsuki so desperately believed to be alive was now standing a few blocks from Katsuki's home, in a shitty alley where only rats can be comfortable leaving. He didn't know what to make of the scene before his eyes. This was the second time in two years that Katsuki had seen his childhood friend. The first one has been just some days ago, during the USJ trip, where a group of fucking villains decide to ambush and attack them. And you had been there.
