SEVENTEEN’s record label PLEDIS Entertainment on Tuesday, Jan. 2, introduced its new K-pop boy group TWS which dropped a pre-debut single titled “Oh Mymy : 7s.”

In a six-minute video, the members shared their respective struggles while practicing and the small triumphs in the form of their family and friends as a support system that led to their nearing debut as a group.

The video snaps to the SEVENTEEN members with PLEDIS executives lined up in a panel as they watch TWS perform before it shifts to the group dancing somewhere abroad.

TWS, which stands for "Twenty-Four Seven With Us," is set to debut on January 22. According to the video, the sextet consists of Dohoon, Kyungmin, Youngjae, Shinyu, Hanjin, and Jihoon.
