Sanghyuk doesn't want to be a lumberjack, or superman, or a cowboy for halloween. Hell, he doesn't even want to be a boy for that matter. He wanted to be everything that it seemed nobody wanted him to be due to his predetermined status based on what hung between his legs. His flaw.  Luckily Hongbin wasn't looking for flawless, just for cinderella.
