Boy group T1419 (Tiilsa Il-gu) has completed its "Mugunghwa Flower Bloom" activity.

T1419 appeared on SBS MTV "THE SHOW," which aired on the afternoon of December 14th, and presented a "Red Light, Green Light" stage.

On this day, T1419 drew admiration by perfectly performing the powerful synchronized dance without any error.

After finishing the stage, T1419 said, "Thanks to Edelweiss, who always supports us, we were able to finish this promotion happily," adding, "We debuted in January and worked hard until this album, 'The Mugunghwa Flower Bloomed.' "I'm so happy and grateful to be able to be with Edelweiss at the beginning and end of 2021," they said.
