On the 25th November episode of Radio звезда on Golden Fishery, Shindong expressed that when he joined Super Junior at the beginning, he was deeply hurt that his looks were vastly inferior compared to the other members.
He then felt that since he couldn't compare in terms of looks, he would become the funniest member in Super Junior. Alas, there were many in Super Junior who could evoke laughter better than him. At one point, he felt depressed since he couldn't establish what role he could play in the group and even thought of quitting.
