JIHYO said, "I was a trainee at JYP Entertainment for about 10 years before making debut. I trained alongside 2AM and 2PM members. I saw all of them making debut."
She resumed, "I actually joined the agency at the same time as SUNMI. I was nine when she debuted as a member of Wonder Girls."

JIHYO said, "Oh, it's probably because I commuted from home to JYP Entertainment every day, wearing my school uniform."
She continued, "One day, one guy asked me if I was a JYP Entertainment trainee. I was surprised that he knew who I was, so I asked him how he knew me."
She went on, "He said that he was a trainee at another agency. But I still don't know who he was. I don't think he ever made debut."
