On the June 9th installment of 'Knowing Brothers', guest Go Ara said of Heechul, "At first, oppa had to go with a chic concept [at SM Entertainment]." He explained, "Before SM Entertainment, I worked at a factory. At the factory, I wasn't chic at all. You always have to have earplugs in. Safety was always first. Everything you see on TV is what I've created."
Seo Jang Hoon joked, "If you kept going, you would've been our country's most good-looking factory worker."
