TST, the group, is in the middle of a comeback countdown for their fans. 

Personal and group teaser images of the new album "COUNTDOWN" were unveiled on December 25 and 26 through the official social networking service channel of the TST.

Members Junghoon and Yonghyeon in the teaser image show the stillness of a handsome atmosphere with their color lenses and shading makeup that accentuates eye contact when they are mature with a languid look.

In group photos, TST's mysterious and dreamy charm shines through the spotlight under colorful lighting and exotic sculptures, as well as fans' expectations for their comeback with a deadly concept opposite to the previous boyish look.

TST is showing signs of drastic change with provocative and wild looks that have not been shown until now through ‘COUNTDOWN’. 

TST’s ‘COUNTDOWN’, which will release new potentials, will be released on various music websites on January 2, 2020.
