Singer Sunmi's reason for failing the SM Entertainment audition was revealed through a broadcast. On the November 8th episode of JTBC's variety show "Knowing Bros," Lee Chan-won, Sunmi, Song Min-jun, and Mimiminu appeared and shared stories from the past. During the broadcast, it was mentioned that Shin Dong and Sunmi were auditioning for SM at the same time.

During the show, Kim Hee-chul said, "I wondered whether Sunmi or Shin Dong would get in, but unfortunately, Shin Dong was accepted," revealing that Sunmi failed the audition while Shin Dong passed. In response, Shin Dong recalled, "I feel sorry for Sunmi because I was first place in that audition. That's how I got cast and debuted, while the casting team took Sunmi to JYP at that time." Shin Dong expressed his regret to Sunmi regarding his acceptance.

Sunmi responded to Shin Dong's comment by saying, "Dong-i was the king of comedy. Honestly, even now, I wonder if it was the kind of comedy that deserved an award." This remark embarrassed Shin Dong. He explained, "Back then, there were top performers in various fields—best looks, best singing, best dancing. I went for dance, but SM suggested that comedy suited me better than dance and asked if I wanted to try applying in that direction."

Shin Dong recalled the atmosphere of the SM audition, saying, "It was hot back then. They were selecting the second Teen Teen Five. That plan fell through, and I ended up joining Super Junior." He added that Sunmi was young and inexperienced at the time. The past stories of Sunmi and Shin Dong highlighted their close friendship.

This broadcast shed light on their past and delivered new facts to fans. Sunmi later went on to work with JYP Entertainment, while Shin Dong debuted under SM Entertainment. Although their paths diverged, the connection from the audition remains memorable.

The story of Sunmi and Shin Dong reminds us once again of the importance of competition and connections formed through auditions. Their experiences will remain an inspiring example for many.
