2 am starts with Mnet's "M Countdown" on November 4th, KBS2's "Music Bank" on the 5th, and MBC's "Show" on the 6th! He appeared on "Music Core" and performed the comeback stages of his new mini-album "(Ballad 21 Autumn/Winter," "I didn't know because I was close by," and "Goodbye."

2 am, who took the stage as a complete group for the first time in seven years, showed off a more mature aspect with modern and sophisticated suit styling. The stage was filled with sweet voices and sensibilities that fit well with the current season.

In particular, 2 am drew admiration by providing perfect harmony through strong teamwork, such as looking into each other's eyes and matching harmonies. With the more sophisticated expressive power and natural expression acting, the viewers' immersion was increased.
