On June 22 episode of Mnet's television show 'Girls' Planet 999', SUNMI and Tiffany Young met with each other.

SUNMI said, "I auditioned for SM Entertainment when I was in the fifth grade in elementary school. I went to the public audition that was held every Saturday."
She resumed, "After the audition, the casting director there called me in. He/she was like, 'Hey, number 1. Come and see me for a minute.'"
Upon listening to her story, Tiffany Young commented, "Oh, that casting director actually scouted me. What a coincidence! This is so cool."

SUNMI said, "I cried every night, because I couldn't understand anything nor say whatever I wanted to say."
Tiffany Young responded, "I know exactly what you mean. When I first made debut, I was really scared to do everything, as my Korean wasn't that good."
She continued, "I remember going to a radio show once. I wanted to say something, but couldn't say anything, since I didn't know how to express them into words in Korean. I felt devastated after coming back home that day."
SUNMI nodded and said, "But in retrospect, I feel like my time in the States was all a good memory."
