Jo Kwon and Lim Seulong of 2AM revealed the story behind their debut on 좋 은아침 (Good Morning) that aired on the 9th.
Jo Kwon stated, "Ever since we were trainees, the members of 2PM and 2AM have been friends and brothers to me. The fans even nicknamed us as 'One Day' by combining 2PM and 2AM."
When MC Jo Hyung Gi asked, "I heard you were originally going to debut as a member of 2PM?" Jo Kwon explained, "When we were trainees, we formed several groups. At first it was a dance group, in which Seulong hyung was also in."
Seulong said "When we were trainees, the members of 2AM and 2PM were active together. And during that time, we created about 7 or 8 combinations [of team members]."
He also explained how Jinwoon and Changmin spent little time as trainees. For JYP, Jung Jinwoon and Lee Changmin only spent 8 months and 3 months, respectively, whereas Jo Kwon was a trainee for eight years and Seulong for three years.
When MC Jo Hyung Gi asked the secret of debuting after spending such a short amount of time as a trainee, Seulong said it was because they passed the audition after demobilization from the military.
On a different note, 2AM released their new song "죽어도 못 보내 (Can't Let You Go)" last month. The emotional ballad of "Can't Let You Go" has been attracting the fans since.
