LOL idk how many actors go to a local theatre rather than a 'top' one for premieres but it would be quite something given how into celebs Koreans are, if someone just randomly shouted a famous person's name so ppl would clear the way and they can go down a diff path or so XD; but prolly frowned upon if you get caught.
Or maybe he'll get famous enough for celeb impersonators or stunt doubles or so assuming he doesnt use a power to 'hide his presence'
