On the September 4 episode, a girl shared her concerns about her sister who constantly brings her down with insults. After listening to the girl's struggles, Kang Daniel revealed, "I also used to get bullied when I was younger because of my looks... I used to get bullied badly in elementary school."
The idol star explained how he overcame the issue, saying, "But ultimately, the self-esteem derives from you. I thought to myself, 'I might be uglier than the others but I'm a better singer and dancer than them. I just need to do well on stage'. I increased my self-esteem like that."
